There are a bunch of trees. However there is L. Scott Stell County Park right down Bush road that has a lot of open air. The issue that you may run into is that the Fort Stewart reservation is close by and they don't allow drones in their airspace
I saw no signage on any of my visits forbidding drones. There are a lot of trees along the canal so I'm not certain if they'd interfere with your drone. It's swampy too so if it crashes you may have to wade.
