One thing I like to do is load my dog and backpacking gear into the plane and go for an adventure. What always holds me back is ground transportation. For example, a friend and I did a trip a couple years ago and it involved renting two vehicles, leaving one at one end of the trail, and then hiking across the mountains from the other end. I’m looking for something that doesn’t require anything but the airplane to accomplish. Dog-friendly is important, so no national parks (those with nearby airports are also too obvious). Any ideas?
