i saw a couple in the park...snuggling under a tree

at 3 this afternoon as i walked the kids to the pool...at 4:30 on the way home, they were still there...dry humping. at 8:30, after the kids were down, i took a bike ride and noticed them still there. a little poke-in-the-park, i guess. but to recap...they were laying under a tree in a park for at least 5.5 hours...no blanket, or anything else, from what i could tell.
