Toll Road Transponder

[kindlethespirit]

I just attach mine next to the rear view mirror and close the top when the car is parked. I wouldn't leave my top down anyway as somebody could do anything to the car when the top is down and you're not around. Not to mention the sun beats up the leather.

I don't know how creative you are, but you can google articles that talk about taking apart the transponder and putting the guts inside your dash or someplace else where it will still receive the signal. I was looking into that, but found out that all Illinois needed was my plates so i just roll without it.
