I'm heading out on my first multi-day trip the second week in June and I'm also staying at campgrounds. I've been backpacking for years so food prep is not much of a hassle. I do a lot of dehydrated whole foods from home but I do plan on picking up a lot of my food as I go. For me this is a part of bicycle touring. Plus a fresh steak and baked potato sounds good at the end of a day.

Hope to see a trip report from ya here. 8)
