37. Try a nearby geo-cache
You never know what weird things people will leave behind -- and you should definitely try to outdo them with something even more bizarre.
38. Make your own beer
Jump in on the craft movement and attend a beer making class together -- brew your own brews!
39. Join the circus
Or at least join the ranks of acrobats and contortionists by trying out an aerial silks class (you know, the one where people shimmy up a ceiling length piece of fabric and then MAGICALLY flip around) or one of its cousins, like a trapeze class. Show off that flexibility.
40. Go on an A-Z food tour
Hop around different restaurants specializing in international cuisine, from A to Z. It'll take a lot more than one date, which takes care of asking them out again: You guys have a project now.
