Lake Travis, Texas, marine channels
 

Would someone happen to know which are the most popular marine band
channels, other than 16, 9, to keep in memory while boating on Lake
Travis? I think Lakeway is 66, but I don't know any of the tow service
channels if there is any. I don't want to load the radio down with too
many, just the most needy and helpful. Also, is there someone who
would gladly give a radio check when asked?
Thanks,
