In addition to testing out 2 handed rods you'll find burgers and drinks all provide free of charge by The Oak Orchard Fly Shop and various other companies showing off their stuff.
Make sure to check out www.speynation.com for details and a detailed map of the location, keep in mind the closest bridge is out so a detour is required.
If you go, wear your GFP t-shirt and you'll get in for free*!!!
* - Spey Nation is already a free event, but wearing your GFP shirt will bring you great luck both on the water and with the ladies!
