i live in orchard park and go to school in Geneseo so it is a pain in the ass but can be avoided. The detour will take you north on 77, and then east on 354. when you get to the 354- 98 junction and the detour turns south, turn north towards attica. You will turn east on main street attica (a confusing intersection. From here on it gets sort of confusing. You continue on main street for about 2 miles and then turn left on east main street. Stay on east main until the road forks, take the left (the road will now be called cadwell). You continue straight and go ove a strange railroad track and the road changes to W. middlebury. At junction 19 you take a left and stay on 19 until you reach a sweeping left, here you want to go straigt onto court street (you don't want to stay on 19). Follow court until you get to 63 here you want to take a right (south). 63 will run into 20A, where if you take a left will take you 390 and back to your route home. This will save you time over the detour, which sucks. I would recommend getting a map if you want to try this as the first time it is a little confusing.
