Join the Oldies But Goodies Classic Cruizers at the Keystone Truck & Tractor Museum on the 1st Saturday morning of each month from April – October. Drive your classic cruiser (all makes & models incl. motorcycles) and meet these owners, see their cars, talk about cars, and listen to music- the Music Van will be playing music. The Keystone Grill opens at 7 am and breakfasts are great! If you have never visited the museum, you have to check it out – 3 acres of cars, trucks, tractors and so much more! It is open from 9 am-5pm.
