I don’t know much about the DFW homeschooling communities, but the Waco/McLennan County area is a great place to live and homeschool in my opinion. I believe we are 100 miles from DFW.
There are nature clubs, CM reading groups, music schools, homeschool sports associations, and plenty of co-ops. We have been here 5 years and appreciate all the opportunities so much. (There is even an Ambleside School starting this fall.)
