Great ideas for a bachelor party needed!!

Hello fellow redditors!! I was just introduced to Reddit yesterday and joined today and here's my first post!

Just found out this week that one of my best friend's is getting married in September. My friends and I were talking about throwing him a great bachelor party. So I thought why not ask here and see if it can generate some good ideas :).

Let me know what ya think!

Edit: I should have clarified more. I was also asking for cities to go to.
