I live near a standalone (not in a rest area) Roy Rogers in New Jersey that has been continuously open since the great ol' days when Roy Rogers were everywhere around here in the 80s. For a long time I looked at it as a novelty of sorts and would go there every once in awhile. I'm sure the novelty aspect kept it afloat for the last two decades for those looking for their Double R Bar Burger, fried chicken and roast beef fixes. Now that Roy's is expanding again, the local franchise owner recently opened a brand new Roy's in Brick only about 5 miles north of their existing location. Although I'm glad to see them popping up again, I think this was a bad move to open so close to their other location because it will dilute some of the novelty crowd and regular business at the existing restaurant before Roy's has the ability to really win a following again. They should have opened another restaurant much further north in the Monmouth County area to not overlap their existing business. I don't want to end up with no Roy's at all due to a poor business decision. Arby's didn't last very long around here, so they should play this market carefully.
As for HoJo's restaurants, the last one I recall was in Asbury Park on the waterfront. I'm sure I ate at one at some point, but can't recall. I can specifically remember the HoJo's in York, PA on US 30 near the I-83 interchange.
