Interestingly, I'm sitting ocean side at this moment in Key West as I first read this. Though I flew down here and am not touring, I've been scoping out possibilities for touring/camping as I've made my way up and down the Keys. Definitely not an overabundance of places to camp from what I've seen and yes, eating out and lodging is rather expensive. And yet, I'm sure it would be a rather unique touring experience for most.
