I forget what it's officially called, but it was such a brilliant idea, I wondered why more places didn't do this. You pay a single fee for the day or for a single trip. If you have a day pass, you can get on and off when ever you like at any of the stops. This idea only made it to my home town last year and I did this trip back in 2008.
Check out some of the great things I got to see from the Bus!
I can't wait to go back!
