The Pennsylvania Trolley Museum will host its “Trucks, Tractors and Trolleys” from 10 a.m. to 5 p.m. Sunday, with the last trolley leaving at 4 p.m. Visitors will have the opportunity to view many different types of trucks, from classic pickups to modern construction trucks. The Washington and Greene County Antique Tractor Association will bring tractors, and 84 Lumber will have one of their tiny houses on display. Those interested in registering their truck or tractor can do so the day of the event. There is no fee to register vehicles, and the first 75 registrants will receive a metal commemorative dash plaque. There also will be trolley rides, tours of the Trolley Display Building and a World War II encampment. Children’s activities will be held in the museum’s Electric Park, weather permitting. Music will be provided by DJ Judy Chickis, with food from Sunny’s Shaved Ice and a small play brick building display by Laura Wells. Admission is $10 for adults, $9 for senior citizens and $7 for 3- to 15-year-olds. Registration will be held from 8:30 a.m. to 3 p.m. For more information, call 724-228-9256 or visit http://www.patrolley.org.
