It was certainly a new folk experience to me!!
Gnomad, are you sure the address is York Terrace? I thought it was on Park Terrace. The way we got to FILO was to go up the steps on the left of the railway station towards the Hospital, then turn left passed the main Hospital entrance, then turn right up North Road and then second left onto Park Terrace and the FILO was further down Park Terrace on the right after a small convenience store.
Sorry to be pedantic but it is a confusing warren of streets of terraced housing in that part of Whitby!
