FSR 121 came in handy when all the spots at the more highly reviewed 689 were taken, at least what we could comfortably see from the road when we pulled in at night. Went back to main road and headed across to 121. A pullout right behind signs on left side at the start of 121 was flat and decent for a last minute night spot. A bit of traffic from what we assume were people like us, trying to find a good spot after dark, but otherwise fine for a quick RV/van spot.
