Guys can't guess what you like to do. If you don't mind talking to them, suggest an event. If they listen, that's a good sign.
Best first date for me, a volksmarch. A big group of people take walk in the country. There are many people, but it's quiet so you can talk, if the guy scares or offends you, ignore him and walk/talk with someone else.
If the guy is oh so interesting and friendly, go to the best second date: UFO hunting. Take a walk in the country at night, with a big piece of sheet metal so you can "call the UFOs" by wobbling the sheet back and forth making a cool noise. Silly, sure, but hey, it worked for Jim and I.
