Just thought I'd post this link to a mapping program to look for suitable ponds or lakes or anything for that matter. Kings Bay or Waycross sounds good to me I saw a couple of lakes around Waycross.
In certain areas, Savannah for example, you can toggle the map to high resolution aerial photos and chose directional views. The resolution is such that you could just about make out a person, and cars are easy to spot and identify if you knew the car make beforehand in the photo.
There is a park in Savannah, (Tom Triplet) where a group of battleship RCers compete with the object to sink the opponent’s battle ship. They shoot BBs at one another.
I’ve never had my sub there but may bring it when the weather starts to warm up.
If I can find the link to the Battleshipers I’ll post.
