By all means let us put our boats in at the pump house on upper Lake Mary. While out having a good time, your vehicle can be safely parked at the pullout on FR3 right near the water. Then just go get it when you need to take the boat out.
There are workers that need access to that pump building. There are other boaters that need to use that close access too. If we don't police ourselves, we can probably expect another 'service' from our forest and we can start paying to use our resources. Please be considerate and don't use the pump house area to leave your vehicle (and one time -- a tent!).
