We've just had this meet up there so many times >.> I don't think we should change it just for that reason (i mean, it's not like we're intentionally trying to dis respect the dead. It's a park for crying out loud! Most parks i've been too (other than city parks with playgrounds) have some sort of memorial for someone/people who have lost their lives).
I hope i'm not sounding mean, but i've never seen hanging out at a park (a memorial park or not) as dis respectful.
