Reading this I was a little ticked that my Pass is no longer was valid at these places. But looking at the list one notices that they are all historical sites. They SHOULD fall under the Texas Historical Comission and not Parks & Wildlife which they are neither.
I guess I can no longer get my
TX State Park Passport stamped at these places. The state really should bring back the passport book. It was a nice gimmick to get people to visit parks that they normally might not have.
