It wouldn’t necessarily have to be random. Just take a cruise down the shoreline and mark spots that could possibly work. Later, when you get back home, look up who owns the land and do a nice write-up with pictures and such of what you’d like to do and how it would(n’t) impact their privacy/lands. If you pick out a bunch of spots, chances are at least one of them would give you the go-ahead. Heck, maybe you could even get some of them to start caching!
