It looks like you are in Burleson. So, there are several options for free introduction to fly fishing classes near you. Bass Pro near DFW airport has a free introduction class each Sat and Sun morning, the Ft Worth Cabela's also started offering classes, but I don't know their schedule. The Dallas Orvis shop will be offering their free Fly Fishing 101 classes most weekend starting in April and going thourgh June. I'm planning to help with the casting classes at several of these sessions.

And, both Dallas and Ft Worth both have very active fly fishing clubs with members that would be happy to help you get started. The Ft Worth club just announced that their annual casting clinic will be May 7. Multiple casting instructors participant and anyone that wants help with their casting skills is welcome to attend.

Good luck!
