I've been to Ephrata a number of times over the years (lived in Chester County, PA for about two decades till Jenn's job moved us to South Jersey from Kennett Square last summer).
I think it's probably around 3 hours each way these days.
I'll probably try to sneak away once this year... Though it's tough with a 3 y/o and 10 month old.
My little bro (I think you might know him, Jay/Jas67) goes often cause he's a lot closer (near Hershey).
Bit of trivia. Nearly a decade ago I posted here how in identical conditions our 05 carbureted sportster ran cooler than my 00 Jackal, but my 07 Sportster ran a bit hotter than my 06 B11.
Just looking at the layout of the motor may suggest differences in cooling, but we learned as kids that science isn't always obvious.
