i am nowhere near equipped for sand...
also im a new member....call me ****** or tyler
BUT
(take this into consideration)
in presque isle county,just south of onaway my family owns 40 acres,that would make a good staging area(and has a 70 foot hill we could mess around with)...and its only minutes away from trails
ive never really tried the trails so i cant say how good they are,but they seem moderately popular.
its only minutes from the presque isle trails and the montmorency county trails
