Here's the best I can do (I'm guessing the streets off mapquest):
Yes, I would exit on
2nd Street and go through town.
Go through downtown and after about 8 lights, turn right on DUBBS Ave or FORRESTER St, I can't tell from the map.
It's a big main drag going to the right, it's right past the museum, and there are signs for the FARM SHOW COMPLEX on the right hand of the street, though they are easy to miss.
Take that down to the dead end by the big parking ramp, and turn left. S/B onto 7th street. Follow that down to where it becomes a single lane, turn right at the light onto McClay street. Go up a few blocks, and the Farm Show Complex is on your right. Turn left at the light for the main drag, S/B Rt22 or North Cameroon street. Go 1 or 2 lights to the end of the Farm Show Complex, and turn left into the parking area, or right to the overflow parking (signs for both)
That's the route I use.
