For all of you flying into Cincinatti for the Midwest trip, here are a few tips that I've found:
1) Try flying into Kentucky or Indianapolis, I have found flights that are VERY VERY CHEAP. You may actually save money flying into one of these smaller airports then flying directly to Cincinatti. If you rent a cheap far for the hour drive from Kentucky (or 2 hours 30 mins Aprox. from Indianapolis) you may save upwards of 50 bucks.
2) For you Greyhound riders, Try to get a student discount. If you are enrolled in any type of school you can get this discount (High School, College, ETC.) Even if you arent, You can probably say you are.
