T.F.
I have not been there in a long time but I don't think there is much to do during this time period.
Our neighbors and a couple of friends have homes there and they don't go anytime past October. Are you taking your own boat? My neighbor took his boat out of Lake Texoma due to the zebra mussels that are causing so many problems.
A few years ago, hubby sponsored a guided fishing trip for a couple of customers and that went well but it was in June.
