I'm driving from Sonoma, CA to Mansfield, PA on I-80, starting out around June 15. I'm thinking I'll drive 200-300 miles a day and camp overnight in my tent in state parks along the way. I'm partial to woods and streams settings. Don't want to go more than a few miles off I-80 but it'd be nice to be out of earshot. Any suggestions (or caveats) most appreciated!
