Sounds like Vermont is the place. They might not even notice until we're gone. I know there's a large National Forest or something about halfway up the state. Woodstock, VT, maybe? Yeah, Green Mountain NF and Finger Lakes NF. http://www.fs.fed.us/r9/gmfl/
Might take a bit of research to find the right place(s) to visit, but that's what the Internet is for. I'll check into things as much as I can.
If you've never been, CDS, the ride out Rt 2 and up Rt 7 is unbe-freaking-utiful. We might have to leave a day early since we'll be stopping all the time. Or you can take the fast, boring Rt 93 to Rt 84 path. We'll get there a day early but we'll still have plenty of film.
