Another way to check your elevation is to call the local airport. I know there are a lot of small airports in texas because I fly into most of them for my job.

Jennifer,
Have you been riding lately? I sold my Blaster so I am stuck with the hunting rig until I get my Polaris done. I am going to try to make it to Badlands one of these weekends.

 

Yeah we went to the dunes a couple of weeks ago and had a good time. Then went to Lake Murray last weekend. Was thinking of going this weekend but i'm not sure with all of the rain we've gotten up here today. Why did you sell the blaster?

 

I was too big for it. Plus after I flipped it at Red River it just motivated me to get something else. I bought a Polaris 400 Scrambler in baskets for $300. It will be my project to get ready to race in the OK cross country series next year. I already bought a new motor that has already been built for trail riding. It will be a slow process as I am going to Hawaii in July but it will be fun.
