I ride it about once a week usually, because it's only a few mins ride from my house. Mostly as part of a quick after work ride. Snake, Waterdown rd, N service rd, lowville, ceadar springs etc....
It's usually clean and the only place that I'm ever worried about in terms of gravel is the last right hand bend (SB) by plains rd. The off road guys throw out some junk with thier trucks every now and then
