Hello to you from Jake, Westin,Shelby, Amber, and the rest of the Mount Valley Class.Okay well we have some questions for you!!! We were looking at pictures of McMurdo Sataion and we saw that there was tractors there.... So we were just wondering what do you use the tractors for?? In the little town that we live in we use tractors for farming, but I'm sure you guys use tractors for completely different reasons. Could you tell us what you use them for. Thanks!
