The university has about three miles of unpaved dirt running trails that pass through the forest near campus. I think these trails should be paved with cement. One reason for paving the trails would be to increase their safety. When it rains, the dirt turns to mud and becomes very slippery, so the runners who use them can slip and fall. Pavement would solve this problem. Also, paving would make the trails look nicer, which would encourage students to use them. Bumps in the trail would be smoothed out and weeds would be paved over, making the trail more attractive to runners.
