First week of May 2006 we trailered up to Delaware (between Phoenix and Copper Harbor), rode about 15 miles and had to cross alot of creeks, but we can say we rode in May in MI!
Put on 4200 miles that winter and actually went to "most" of my classes, ha.
Have ridden alot of Easter weekends, the buffet at Mariner North is great, but not always the best plan if the trails are rough.
