I am usually out in the Warthen/ Sheffler/ Poodle Creek/ Lawrence/ Butler/ Kirk area unless I'm with a buddy; then we are out west of Junction City. Anyway, the sharpness of gravel hasn't been an issue for me, but just the presence of it in the winter as well as all manner of storm debris has me liking the notion of 28's just for a bit more stability.
B. Carfree: Butler is a great, and very pretty, conditioning ride...
