I need five (5) unique and creative bachelor party ideas for a weekend
in May in Denver, Colorado. It is for a group of 6-8 men in their mid
20s. The guidlines are these:
1. Generic bar hopping is too unoriginal;
2. Not interested in paintball;
3. Strippers are to be avoided;
4. Already thought of going up to Blackhawk, Colorado (but you may
reccomend specifics in blackhawk);
5. Already thought about renting a bus to take us around.

We are all "normal" guys who like bars & clubs; we were all roommates
in college at one point.

A satisfactory answer will provide five original, fun ideas.

I am not a paid research but here is my comments anyway.  I have to
live vicariously through you.
1.  Rent box seats at a Rockies baseball game. 
2.  Golfing Outing
3.  Rent a small bar and throw in some Poker.

Get a massage for each guy with a CTE (Certified Tantra Educator) and
you will experience something unique to talk about a life time.

Good luck!
