Don,
Good info to have in our cellphones.
This phone number varies from the one in the Roster. I'd imagine the Roster number is for the District III Dispatch, and the 334 number is for the Montgomery Dispatch. It's worth checking and posting the best numbers in the updated Roster.
As a related matter, the commanding Marine Police officer over Lake Martin once told me, very specifically, that they DO NOT monitor Marine VHF Channels.
We can communicate with each other, but don't expect any VHF interaction with the MP or any pontoon boats.
It's really rather disappointing.
Jim
