i live in DC, and have a week off grad school, and just got laid off my internship. i was thinking of going to new orleans but it’s too expensive right now to take a plan on short notice. what ski slopes can i get to without a car at this point?

I have a 1997 Ski Doo MXZ 440 liquid cooled and gas is getting in the oil tank. I have put about 1500-2000 miles on the sled and have not had to add oil to it (tank is always full). Oil is light bluish green. My brother figured gas is getting in the oil tank because of the smell of the oil. What could be causing this problem?
Sled is also hard starting. Is this part of the oil/gas problem?
