I've never really been on vacation before..my summers usually consist of:
Exploring, just pick a direction and start walking
Swimming-we swim in the river up the road from here
Have cookouts-invite some friends, tell them to bring their favorite foods, build a fire and roast hot dogs or something..
Or-pitch a tent in your front yard and go camping.
Of course, we live in the middle of nowhere and we are surrounded by trees, so we can do these things without intruding on neighbors..
