I just noticed this thread so... why not.
90% of the time I ride with Mrs. TakingMyTime. Our usual starting off point is on the SGRT near El Dorado Park. Depending on our mood, we'll ride the SGRT South to PCH in Seal Beach and then go to either Bolsa Chica, Huntington Cliffs (Seapoint) or the Huntington Pier and back. Strictly riding for fitness and companionship.
