The annual Chumduffy Playday in Smethport PA (north-western in the vicinity of Buffalo and Pittsburgh) is on this year on Jim Duffy's patch. Jim and the whole Duffy team have a lot of equipment which they love to see be run (dozers, scrapers, graders, other bits and pieces) or you can bring your own. Ample parking for cars and lowboys, ample play area, famous Duffy hospitality. Don't miss out!
D2s, D4s, D6s (new and old), D8s, a D9, a 16 grader (D8Pete) which is like a D8 on wheels, tractor-drawn scrapers, a Northwest (but you need to get certified by Jim and team on that - not for novices like me : ), and a whole field full of "sleeping beauties" to marvel at. If you bring a rig and you're not a fan of walking (it's a nice walk across the field in the summer sunshine), also bring a golf cart as it's about a 15min walk from the parking/sitting area to the play area.
Feel free to post if you think you're coming or are just interested and tell your friends/bring your friends.
About 2 hours from Buffalo, 3 from Pittsburgh
