i ride up there a lot, but i never go any further north than sand lake. I think the white pine from N Park (in comstock park) to Sand lake is 22 miles. If you go south from N Park down through riverside park to ann st to monroe south to bridge (downtown GR) it is another 4.5 i think. if you did all that round trip you'd be at 53 or so. if i was trying to get extra miles, i would do a loop at sand lake over to myers lake south to 16 mile west to shaner back north to sand lake. that would add 14 or so miles and get you pretty close. shaner is pretty good to ride, not much traffic. myers lake will have a little more traffic, but shouldn't be too bad. i would avoid 14 mile and 17 mile due to traffic
one of these days i'll trek up to howard city, i just haven't done it yet
why did they say I needed this degree?
