My names is James Doughty. I grew up in Somesville when there were many high schools on the island. Somesville in the town of Mt. Desert. Our whole high school had about 15 boys and basketball was very important to us. I rermember the day when Carlo Nimfi, charles leland and I decided we should have a mascot, Carlo had seen newsreels of a California team who were called Trojans. We decided that would be appropiate. So that' how you got your nickname. What I really want to know is why has the prunounciation of Mt. Desert changed? By the way I'm 88 years old.
