Thank you, guys. I read on here somewhere (can't remember where!) that smoking was banned on Naples beaches - and there's lots of general website stuff about a proposed ban on smoking at Naples beaches (though nothing to confirm that it happened!) I also saw an image of a sign for Delnor Wiggins, which said no smoking. It's not a matter of life or death (lol!) - it's just that if you can't do something, you want to do that thing and your head fills with that 'need' and you don't relax!
We generally take a bottle, containing a little water, with us, to put our butts in. Once, in the dark in San Francisco, I reached down in the car and picked up water to drink and got the wrong bottle! Urrrrrrrggghhhhhhhhh!
