Even if you want to do something more interesting than coffee, find something better than “let’s go together to a remote area where no one will hear you scream or find your body” or even just “you’ll be stuck the whole afternoon with no way out if it turns out you don’t like me.” If you want to do something like that, I would recommend a climbing gym or something like that instead. It’s public and it’s easy to leave, two things you should make sure to include in a first date.
Well it was just the first idea close to hiking that popped in my mind (that fit the public and easy to leave criterion). I personally wouldn’t do that since a) I’m a couch potato and b) I’m happily married (and haven’t really dated before that).
