You know we don’t need any lakes that big. We have piece of the Atlantic Ocean, you may have heard of it. The Gulf of Mexico. You can get 300 miles from shore in it. You can fish in it, boat on it, and even surf.. sometimes. It never gets quite so calm as Gitichigoomee. But the surfing makes up for that.
It is pretty shallow near shore and the shorelines are not steep, at least in Texas, but pretty much all around it. But it does get pretty deep in the middle. Deep enough that German subs would hide there during the daytime, in the early days of WWII. They’d move closer to shore to find targets, which was easy because most of ‘em would be going to/coming from Galveston or Corpus in Texas. The oil tankers and grain haulers at least.
Not only that, but we can boat on the Gulf Coast year round.
Other than that, your place might be okay....
