Dungeon Master's Log - 1e campaign, part 2

In the intro to my 1e campaign post I introduced the characters and told how they went In Search of the Unknown. Our intrepid adventurers ended the first session bedded down in the hidden supply room making tea over a makeshift fire and jury-rigging light sources together. The next day they started out by leaving an iron spike pointing to the secret door to the supply room and supplementing their 'always take the left' rule with - a trail of nails to mark where they had been.
  That's right, they still had no mapping materials and, jerk that I am, if your character doesn't have mapping materials, you can't make a map.
  The wandered around quite well, although the sloping floors, fake stairs, and maze-like layout surprisingly enough confused the heck out of them. Realizing they had no idea how to get back to the entrance they started hoping for loot consisting of beef jerky (yes, they have had characters starve before. No, I don't think that is mean). Before the end of the session the chuckles after asking 'is giant spider good to eat?' were a bit forced.
  Then they hit the door maze. They went round and round, popping out into the labyrinth of twisting tunnels. Finally they found a door and - were back in the door maze. After another hour of game time they simply sat down, ate a meal, set up a guard rotation and slept in a 10' x 10' room with a door in the middle of each wall.
  During the session they killed a giant spider, 2 kobolds, and 4 skeletons. The loot included a spear that the One Man Army is already fond of, about 15 g.p. worth of various coins, a silver necklace with amulet, and a plain gold ring.
  All 4 boys really enjoyed themselves, too.

Intro to my new 1e Campaign

OF COURSE I am running a 1st edition AD&D campaign! I've been running one since 1978, why stop now?
  The rules? My house rules (currently being written up as Far Realms, an OSRIC supplement) but the specifics are
  Character Creation: 3d6 in order; roll three sets and pick the set you like. Any set with more than two stats under 5 or with nothing over a 7 may be discarded. I prefer you create characters with me so we can work on basic backstory together.
  This campaign is special, though, since it consists of my 4 older sons! J is playing a Druid, A is playing a One Man Army (half-elf fighter/cleric/magic-user), S is playing an Assassin (using my house rules he is Chaotic Neutral) who is so far passing himself off as a thief, and N is playing a monk. He rolled monk stats on 3d6 in order on his first attempt, making him a very happy young man.
  To really give them the entire experience I am running them through In Search of the Unknown, although I have thrown in a few hooks for my own campaign, such as notes about cities, villains, etc. here and there. They went through character creation with me one at a time, we worked up simple backstories, then they bought armor, weapons, and equipment. They met through mutual friends, a mentor, and a job posting, and headed out.
  The pros; they made sure they had enough food and water for several days without me prompting them. They had a good mix of weapons, essentials like 10' poles and iron spikes, and even extra clothes in case they got wet!
  The cons; they brought a grand total of 1 torch and nothing to write on or with.
  They had a single random encounter in the wilderness, a stag, so they did not use rations on their way to the dungeon.
  They spent a lot of time checking out the bodies at the first junction, not realizing they were running out of torch.
  Their first random encounter check was positive and they fought 2 orcs, killing them handily and taking their lantern.
  I did not allow them to map, since they didn't have anything to map with. Within 1 hour of game time, they were lost - this was BEFORE they hit the door maze! Almost out of oil for their looted lantern they got very lucky and the half-elf found the secret door to the hidden supply room. After a fight with the evil gnome raiders inside, they settled down to rest and made torches from the materials in the room.
  They are having a great time and spent an hour recounting the adventure and planning ahead.
