Is there a place in DC Metro Area (preferably in NoVA) where I can rent skis, boots, poles for a season? My friends from NY told me they have a lot of places offering such an opportunity. I asked in Ski Chalet at Tyson's already and got a negative answer.
The on-slope rental shops at some ski resorts also offer season-long rentals at a discount, although that would limit you to visiting just that resort. If you primarily visit one resort, you can try calling them to see what they offer.
Hope that helps,
