Last year there was a lot of talk about the type of person who rides 105 miles in the desert. Aside from "crazy" we used words like "driven", "Type A personality", and "determined". I found this little personality test on the web. This description is for Tom. Click the link on the bottom to take a very short test to determine your personality.
