Ireland, in my opinion, the Syracuse show is well worth attending, particularly since you will be in Rochester and will only be about 80 miles (1 1/2 hour) from the NY State fairgrounds via the NYS Thruway. There is a good variety of O gauge product there, with both dealer and private offerings. Several forum members sell / display / operate there, including some OGR Forum sponsors.
Parking is onsite and free. Kids 15 and under are free.
Go for it - I live in the Rochester area and go there just about every year, usually with a car load of grandkids.
Enjoy!
