I thought we could all post changes to the ramp situation here. If you notice that one is open that isn't listed, or find out that one closed, just list all open ramps in a reply. If you have additional info about these ramps, feel free to add that, too. This way, we find out about changes quicker.
I just called the COE and we're down to 6 open ramps:
Big Creek
Charleston (3 open ramps, 1 floating dock)
East Bank
Little Hall
Shoal Creek
Tidwell (1 open ramp)
