I found Outdoor Pro Shops in Garland on 2825 Belt Line Rd # 105 (972) 414-1969. In fact, I bought a bow from them with Christmas money
They are a Mathews distributor as well as other bows. They have an indoor 20 yd range.
Yesterday I visited North Texas Archery in Farmersville. (1203 Hwy 380 Suite 133
Farmersville, TX 75442, Phone: 972.784.BOWS). Really nice place and great people. Best indoor range (20 yd) I have been to. They have a real nice store and it looks like great service.
