Need ideas for things to do?

So my boyfriend works till seven tomorrow night and we are going to hang out after he is done, but I don't know what we could do. We live in a small, crappy town so there is nothing to do around here. We both are also in college so we don't want to spend money. I was thinking of maybe having a picnic because it's someone romantic and we would be able to just talk with each other and chill. But I'm not sure if it would be to late to have a picnic.
