I was out there 2 weekends ago, very windy.

Anyway, I was curious...does anyone fish those canals in the thick southern parts or is all the fishing up in the NW area where it is open/hydrilla/etc?

Depends on what you mean by thick vegatation: if you are talking about the fields of spatterdock than no to the the southern end. Basically, if there is weed and open water around it, it is good fishing. If it is comepletely filled with spatterdock, you would be wasting time.
