on sunday i'll be dming a game for a meetup.com group. i'm just covering for someone else and i have my own campaign i run on wednesdays so i don't have anything prepared. i just want to download a nice quick and dirty dungeon crawl. but some of the players are serious hard core fanboys and i'm sure they've read everything from the wizards.com site including all the downloadable adventures. any recomendations for a good place to download an adventure? ideally it would be for 1st level pc's and easily scalable because we could have anywhere from 4 to 8 players.
