Take 365 east to 49 east to 12 north to 8 north. You p/u 365 @ exit 33 off the T-way. It's a 4 lane for about 10 miles +/- @ 55 mph. Stay on 365 and don't get off it (just past Rome exits), rather look for/stay on the 4 lane as it turns into/merges w/ 49 east towards Utica. Becomes 70 mph for approx 10 more miles. Stay on 49 east until you see signs for 8/12 north.365/49 run parallel to 90, flat and only3 lights on it for the entire time, no towns or sharp turns. Once on 8/12, go approx 5 miles (good pull-but 4 lane w/ add'l slow truck lane) and 8 north branches off to the right at top of hill. FWIW- there is a Wal_Mart/Lowes/Applebees/Bass Pro/BJ's & BJ's gas on right as soon as you get on 8/12 north. After you get off 8/12 onto 8, you'll start down hill for approx 8 miles into the village of Poland. Good size down hill last couple miles.Turn left in village to stay on 8 north. AWESOME campgrounds at exit 33 (Villages @ Turning Stone) and just before you cross the bridge into Poland (West Canada Creek Campsites).
Also, if you need gas/diesel once you get off the T-way, there is 2 Sav-on stations on 365 east. One sells diesel only, the other is full blown gas/connivence store about 1 miles from the T-way and at same light opposite each other. Be on look out for Amish buggies on 8/12, 8.
