In Denton (45 minutes north) there is a 9 a.m. Saturday practice on the lawn near the green houses on the campus of Texas Women's University led by a long time montessori teacher and tai chi practitioner.
On Wed morning at 9 a.m. there is Tai Chi in the park near Arts Fifth Avenue at Allen and Fifth Avenue an E/W street between 8th Ave and Hemphill on the near south side. There is a charge for the class. Held at nearby park.
Can't find exactly an open practice in a park in Fort Worth ....if you do, please let me know
