With the PA Turnpike a constant presence in my life, I need to figure out the best way to mount an EZ-Pass to my bike. I've read through some of the older threads on the topic, and it sounds like an exterior transponder mounted to the front forks works well. Does anyone happen to have a picture what this looks like?

I'm also considering this EZ Toll product (a mesh bag that ties onto the bike): http://www.youtube.com/watch?v=9dkpOsbZnos

Does anyone have any experience with this solution? It seems like an inexpensive option if it works.

I don't have a map bag, and I'm not ready to spend $50+ on a special mount just for EZ-Pass.
