My local beach is relatively uncrowded, even in the summer, and I go early in the morning in summer also. I seldom interact with any of the tourists, and I do my best to steer clear of them. It's annoying the way all the little kids scream at the sight of a wave, makes me keep looking over my shoulder wondering if it's a tsumani or something. Of course, I was out there screaming like a little girl myself the other day

--there were creatures in the water bumping against my legs. A couple of jellyfish, something else that felt like a fish with a hard, bony head, and I stepped on a couple of crabs.
The tourists and their trash piss me off, too. Cigarette butts, fishing line, empty bait containers, the list goes on and on. When we first moved down here, the DH and I used to take a 3 mile walk on the beach in the mornings (before surfing) and fill up bags with trash left behind by tourists. I've got foot problems now (fallen arches) so we only clean up the immediate area around where we're surfing now.
Last fall, there was an onshore flow for a few days, and all of the cigarette butts left behind all summer got washed up on the beach all at once. It was appalling. A group of local volunteers got together and picked them all up, fortunately.
But hey, the water's 80 degrees down here now, so even if the surf forecast calls for ankle high surf, I'll be out there.
I dunno, I think the wetsuit's kind of flattering, actually. But I'm not looking forward to wearing it again.
