A little of everything
The Champaign County portion is beautiful and well maintained. Clark County section is quite a bit different. The new extention, North of Urbana the gravel section, begins and winds you through some beautiful, gently rolling farm land with long, unobstructed views well clear of US 68. Unfortunately, as you enter Clark County to the South you are faced with getting through Springfield. It's unfortunate that there isn't a better way. I've encountered plenty of broken glass, youths throwing firecrackers at me, verbal posturing from malcontents, etc. It's a bit like a demilitarized zone until you get back on dedicated bike bath well South of Springfield. Urban blight left behind, points south through Yellow Springs and to Xenia are a joy. Look for route alternatives that bypass City of Springfield entirely.
At the bottom of my list, so far...
We started this trail in Urbana and ended in Springfield. We were disappointed on a few levels. The trail is a straight shot down to Springfield with almost no scenic views the entire way. It's basically cornfields, railroad tracks and flat lands. The trail crosses many streets, some dangerous, so one has to be very careful when crossing. We also heard several gun shots at a particular point, which was unnerving, to say the least! We were told to not go all the way into Springfield because it's a seedy part of town. We went within two miles of downtown and the neighborhood became less than desirable and at that point we turned around. Sadly, the only plus to this route is that it's flat, well paved and an easy ride. It's pretty much full sun the whole way too, which can be a good thing or not, depending on the temperature outside. Sunscreen may be needed...
