Four long trips between 19-21 agree. Now I'm old and fat and my back won't take the floor sleeping. Or the smell. That is a funky business.know plenty of folks that did tours in their early 20's in a broke down van sleeping in it or on somebody's floor. Most look back fondly on those experiences but had to get real as they headed towards 30.
When looking back, fondly isn't the work I'd use. More like glad-to-have-emerged-from-the-tempest-scarred-and-shellshocked.
