That's the 4th Saturday; the event is always on the 4th Saturday of October for decades.
(There are five Saturdays in Oct. 2022 and it is NOT the last weekend.)
It was an epic Autumn Trails old car weekend #58 in 2021, hosted by the Autumn Trails As and
many Ford Model A clubs across three states, and the 63rd year for Autumn Trails hosted by the Autumn Trails Association.
Please Let Ron Taylor know if you're interested in going.
