Your exif says you shot with a 70mm, which 70 if you don't mind? Maybe my imagination is playing tricks on me but it seems there's a ever so slight curvature at the horizon? I'm thinking it can't be that far away, LOL, but I could be wrong! I know nothing about that part of the US, I was only on Lake Erie once, my wifes from Akron Ohio, and even that "little lake" was BIG WATER to me ;~)
