I got an email about the Possum Pedal out at Graham June 4.   I did this ride a couple years back on an DF.  It was a well supported ride and Graham really seems to know how to make a great weekend.
 
The Possum Pedal offers rides of 6, 21, 27, 34, 50, 65 and 79 miles.  Route for any skill level.  
 
Finish line activities include the Second Annual Food Truck Championship of Texas, live music, fun activities for kids and the entire family, and finish with an outdoor concert with Casey Donahew Band and Pat Green, just a short walk down 3rd Street. Visit the Food Truck Championship of Texas website for more information or to purchase tickets to the concert. The concert tickets are $35 day of or pre-order online for $31.  
 
The first 400 riders receive a free commemorative t-shirt and food truck voucher good at the Food Truck Championship of Texas!
