Btw you were over 15 , so that's 4 points on your Driving license. DON'T EVEN THINK OF PAYING IT . in 10 points your license will be gone (in NY, don't know about texas).
I paid 375 to lawyer on same area , same speeding limit (mine was 72 on 55 ) but lawyer changed it to parking ticket !!! I don't think your local lawyer will not take that case, they don't want to fly so far for 1 case, unless you pay plane fare.
