Sure, I can see it, but if that were the cause, we wouldn't see people do it at Grayton. I do think that seeing people in general, leaving their crap out on the beach for a week at a time, sparks ignite in people's minds. I do understand your thought, but I just point out that it isn't due to rentals in particular, but the rentals left out overnight surely add to the problems. ;-)
Ah, the complexity of problem analysis! All I can say is I was just on the phone with my sister (discussing the new Harry Potter book, among many things) and started jumping up and down saying "6 weeks to vacation! 6 weeks to vacation"!
Kind of sad actually but it's all I have to get me going to work this afternoon.....;-)
