I can't speak to the Texas requirements....
but until last year Alabama had a law on the books that no out-of-state universities could have license plates. Not sure what legislator thought that was worth ensconcing in law back in the day, but it was there.
State has several grads in the legislature that had been trying to roll back that statute for years (at the urging of our alumni association, of course). We pow-wowed with other schools in the region and finally got enough people to realize that this was an opportunity to direct free money to the state's general fund, and the law was changed last year.
Now, as far as the current process, it does require 1,000 pre-commitments, and they have to pay the money up front, so this is no small effort. From what I can tell there can be a lower requirement of 250 pre-commitments if you accept a simpler design.
I was expecting some of the other nearby schools to have their own drives going, particularly Tennessee and UGA. So far it's just us and y'all, though, and I don't think you guys are going to come anywhere near the 1,000 mark.
