Did anyone travel to the Vermont ralley from Texas? If so did you take roads other than Super Slabs and if so which ones?

My family is having a get together this summer and my wife and I'd like to take the bikes but do not want to travel the interstates but don't have a whole lot of time to do this. We'd really rather not fly and rent or drive the car if we can help it. 2 wheels are so much more fun!

Any ideas will e appreciated.
