I recently visited the US and had the opportunity to see and ride on RLH 14 at the Nittany Antique Machinery Fair on Friday 2nd June.
By way of explanation it wouldn't start in the morning as it had a flat battery but by the afternoon was giving rides round the site at Penn's Cave.
I have some photos if there is any interest - not much different from the ones on the website from 2012. The interior paintwork could do with some attention.
