I live in E. Pa. and like most above have said; full of people, small to large animals of all varieties, kids and the occasional lost wandering soul........................so, instead, I ride a baby bottom smooth tarmac loop in a nice residential area. Its 2.6 miles and usually do it 10X's give or take.
Yes, boring as hell but safe after being hit (not badly) 3 times in traffic streets.
Now a dedicated road bikes only trail approx. 8 feet wide with inclines would be awesome. Posted MPH would be 45-50.
