We wrapped up the second leg of Shawn's D&D 4th campaign last night with a classic dungeon crawl.  Lots of fun traps and interesting puzzles, including "one size only fits one" people skins that we had to match up to their former (now skinned) owners.  And a nice little battle with a mind flayer to top it off. 

And after all my wah wah about the lack of real rp in the campaign, it was this session that was the most fun.  I'm trying to figure out why.
