Hey Ron,
I went to horseshoe today, what a little gem!! I took some photos (though my phone died shortly after arriving). When I get back home on Sunday, I'll give you the details
There were cucumbers, tons of emeralds, blue legs, orange claws, rock anemones, etc. I wasn't expecting that drop in horseshoe.. I wonder how deep it drops, I saw some huge fish eye balling me right where it drops down and gets dark lol I was to chicken to leave the edges.
