This is a great site for anyone contemplating riding at Moose Mountain:

Couple weeks ago a bunch of us did Moosepackers to Ridgeline (which is a new trail this year that bypasses most of boggy Tom Snow) on our XC bikes. Great fun. Ridgeline is a great new trail. Not for a DH bike though as there's a fair bit of climbing to get to the downhill sections.
