Just reading through this again...Tray Mountain may have been a little undersold. The run up the mountain between Chimney Mountain Rd and Tray Gap is fun. It has a few off camber spots which Old Bucktown does not. Definitely air down, it's bumpy. It's a fun ride up, nothing too challenging. If you are new you may need a spotter in a few places.
The three places to access Tray from the west (17/75) are all easy drives up a gravel road. Just making sure you don't miss out on the fun if you drive up there and find only gravel roads.
