That sounds pretty damn perfect. Last year I went to a bachelor party in Colorado that did something similar -- rafting and they provided coolers of beer.  Manly as you say, and at the end of the day you feel like you EARNED that beer; it's not just you starting to drink at 9pm on a Saturday.

Just had my bachelor's party a couple weeks ago in Minneapolis. It was a FANTASTIC day! Started with indoor paintball (and jaeger-bombs), after lunch we went to a place where you brew your own beer, had dinner at a comedy club and went to the show after, ended at a strip club.

The paintball was cool because there were some guys there I didn't know that well and it was a bonding experience (especially when the game came around that was everybody versus the groom-to-be). The beer making was awesome because they had all the ingredients and everything all set up so it just took about an hour to brew it (we went back 2 weekends later and bottled the beer which tasted great). The comedy club was a great idea too because dinner was great and the headliner of the show was fantastic (and a few drinks made the opening acts tolerable as well).

All this was done in Minneapolis.
