The Georgia State Parks service has selected 11 parks with bike trails totaling almost 70 miles. If you ride all 11 trails and submit the card (stamped at each park) as proof, you get a t-shirt.
AllenG has already expressed an interest in doing this, and I'm going to knock out my first park tomorrow.
Are there any other GA foosters interested in doing this?
Also, any other states do anything similar?
