There are horses (actually they are ponies) on the beach. I know this is a sucky picture because it's a picture of a picture, but you can see that the pony is having a little prance in the ocean with the tourists. Here's some info about this amazing national park where I am from on the Eastern shore of Maryland. I guess they are really horses, but we always call them ponies.
They are actually kind of a nuisance because they leave big horse poop piles on the beach and they will walk right onto your beach blanket and demand your lunch from you, but that's really because people have fed them too much and they are completely uninhibited.
The picture is from a card my mom sent me, and her last line was 'Do you have horses on your beach?'
So if you ever get a chance to go to Assateague Island is an awesome place to see some really cool wildlife.
