Cruise some of old Hwy 80. Climb some mountains. Get back close to old Mexico. Come back around.
A quick SD backcountry ride up into the mountains. Stop at Barona for breakfast and pie in Julian. Don't forget Dudley's! Enjoy the day and some lightly traveled rural roads. Watch out for weekend crazies.
Quick loop up Crest, Lyons Valley, and back. Enjoy the twists! Usually light traffic. Watch out near the casino.
