Dinner club: getting a group or couple of people together each month or twice a month to try and review different restaurants in town. This would be fun and come to think of it Matt and I could probably get away with doing this along side one of the other clubs.
Cooking club: kind of like the dinner club. There would be a set idea or country and then each person involved would be instructed on what course they would need to make (appetizer, entree, dessert, etc.). This would be a fun way to have a planned potluck. The only challenge I see is that many of our friends don't cook that often :(
Book club: getting a group of people together each month with the objective of having read and being able to review a book. This could be a challenge with many of our friends not having a ton of time to read, but it might work.
Debate-ish club: getting a group of people and discussing world view, philosophy, environmental issues, how to toss a midget correctly and get the most distance, etc. This would be fun and easy because we do this with a lot of our friends now. The challenging part would be to make sure that there are differing opinions represented.
Crocheting club: ok, I know I'm pushing it. I don't think any of my friends would be interested in this.
Gaming club: This would be for people that are not as into computer games. A group of people get together and play board, trivia, and other games.
I know there are more clubs that we have discussed, but these are the ones that come to mind. We should be making up our minds soon, and when we do I will post what we have decided.
