I thought perhaps since OP didn’t specify GMRS repeaters in their statement (I fully acknowledge that’s likely what they were talking about). it would be worth mentioning ham repeaters as well. Which according to Repeater Book there are 1,707 Texas repeaters in the database. Add the 112 GMRS repeaters or 263 if you count stale and offline repeaters listed here, and all the repeaters that are not listed here it would be safe to say Texas has a significant number of repeaters. Hopefully OP finds this encouraging and if there are no repeaters in their area because like it was mentioned it’s a big place, do as @OffRoaderX often says you can be the pillar of your community and add one.
