Tarp line: best reason EVER to have kids.
I suppose they have to be older than nine, though....
As for sunshade space, we usually hang out with a couple other families. Two of us do tarp line, the other grownups (yeah, usually moms) have the kids in the AM, and we all meet at the festival after things are set up. It makes for tired dads most days, but nightgrass has that effect on us anyway. Tarp line has never been anything but interesting and fun. There's always a good conversation, and sometimes people show up and start playing music. Later, a nap under the shade is often an option. One the music gets going, the tiredness sort of evaporates.
