I've never done K but I want to. One of my favorite experiences smoking pot though (and it gets hard to pick a favorite after a more than a few months) was the first time I watched a movie high. Me and a buddy smoke a J in the middle of bourne identity and all of a sudden I could actually feel the intensity building and releasing, instead of just hearing lines. Watching movies stoned has become a favorite activity of mine and ketamine sounds great. I read one guy on here a while back talking about how he played halo on ketamine and would get upset everytime he got killed because he felt like it was his fault the little dude died. Sounds great.
