college student needs help - [Thaddeus Smith]

My name is Thaddeus Smith and I am a college student at University of Wisconsin Whitewater. I'm doing a backgrounder for my Public Relations class and are topic is Two-wheel travel and the question I have to answer is "What will make people select a two-wheel itinerary for a vacation?" So if you can help me out with some info. on this topic or any other topic I would appreciate.
Thank you
Thaddeus Smith
