Date Ideas for high school couple?

My boyfriend and I are both in high school (I'm 16, he's 15) and we've run out of things to do for this Friday. We've been dating for three months, we've already been to the mall and movies a million times, went roller skating, climbed trees, went to the beach, chilled at each others houses, explored downtown, went to a car show, threw a party, made cookies, even did some parkour together and scaled a building, etc. We were going to go ice skating or paintballing but the places are too far away and neither of us has a car and we live in florida so its not like we can go skate on a random lake or something. So, please please please, help me think of something really fun to do!!
