State Route 77
South of Mammoth is a down hill passing lane. Posted limit 55, very easy to go 70 to 75 if you don’t ride your brake.. This highway is a major drug artery, that’s why there are so many DPS officers there. They will stop you for anything then ask you a lot of questions. Luckily I wasn’t stopped for speed, just a faded license plate tab. Officer was polite, though. Be careful in Mammoth!
