If you guys are experienced boarders that love back country boarding and glades, definitely hit up Jay Peak. We were there last weekend and it was amazing. Definitely not a beginner mountain, though. Killington is cool, because you can use the lift ticket over at Pico Mountain as well...it's next door and a nice easy mountain. I personally have never been to Killington yet, we're going there this week actually. But Pico I have been to a few times, and it's a nice mountain with lots of blues. Some experienced riders may find it boring. It's really all about your skill level.
