Model A's hills and valleys

[therupperts]

On our trip to the Grand Canyon this month I noticed a total of three Model A's on a trip from Illinois to Arizona. All three of these A's were found in the mountains in Arizona. Would these have had to have juice brakes, modern transmissions and souped up engines to drive this terrain? Just wondering since I couldn't stop and check out their cars. Glad to see someone is driving them though. Good for you whoever you were.
