Cool! We sound like you guys. We brought the girls (5yo and 2yo) to moe.down this year... we went with friends that have two girls the same age, and it was really fun (albeit much more work with the kids).
We've missed grayfox for the last few years, which is a shame, I grew up right near there and I love the area. Hopefully next summer. Although we're also talking about going to Mountain Jam, and moe.down... so many festivals, so little time!!!
I have to say that Greyfox at it's new site, is not nearly as beautiful. It's a bit more convenient (no getting stuck at the bottom of the hill when it rains), but it lacks those amazing Greyfox sunsets. The music is still great.
We're going to keep it small this summer, since we'll have a little one in tow. He'll be 6 months for our first festival in June. I can't wait to bring him and expose him to great music and great people!
