I used Terry Ramp on Saturday. Put in 2pm ish and out around 8pm ish. Traffic wasn't as bad as the other ramps, still the usual problems, people loading and unloading, packing up while still parked on the ramp etc.
However, This ramp has no breakwater and is open directly to the lake. I liked that it had a dock, but your boat gets pounded while tied up. Also someone in a big boat passed right by the bouy's as I was driving the boat in. I thought the huge wave was going to float my little tin boat right over the trailer.
I hate paying $20 to launch my boat but at least at harbor bay the ramp is in protected water.
Once I fought to get on the lake, it was a mad house Sat .. not much fun for me. I probably wouldn't go out in the main lake again on a weekend until the other lakes open up and take some pressure off.
-good luck and be careful out there.
