I live in fenton now, but will be moving soon to the olivette area or into the city. (New job, got the bike, now time to get a new place!)
I ride all over. My favorite I've done in the area so far is (in short terms) hit the south end of hwy 109, ride it all the way north, hit hwy T and continue onto hwy V, north on 47 into Washington, across the river, hop on 94 east all the way back to 64/40 and re-join the north end of 109, and finally hit it back south taking some curvy back roads into the home town. Great scenic ride, hilly, curvy, good stuff. Gonna get a ton of riding in once the salt is washed away. Hwy T, hwy V, and hwy 94 are HIGHLY recommended if y'all haven't ridden them.
Want to ride out to "Frankenstein" MO, a bit west of here just to snap a pic by the sign. Probably hit 100 out that way, I hear it's nice. That's the first ride planned. The second is the Great River Road, Lewis/Clark, etc.
This weather should be exciting... Ice and somewhere between 3"-12" haha, not sure anyone really knows.
