I think you're at college Jamie, so I'm not sure if you have the props necessary, but I'd say leisurely biking to a destination where you can take lots of breaks to chat, get water, etc.
Or if you don't have bikes, rollerblading would be cool too.
And if you don't have either of those, you two can walk to a destination. Lot's of time to get to know each other .
If you live in the dorms and both are on meal plans, perhaps you can go to a destination that's near a dining hall that you don't normally eat at? That way you guys can get a meal together, plus something else.
Hmm, can't think of much else without money.
Anywho, good luck!
