Well, after driving around a bit, we settle on Desert Tortoise Road (it was still pretty busy, but it worked). Got three dives in, found some depth pretty easily- hit around 70 feet and it kept going, but we didn't. It was getting dark fast down there. The vis was spotty- patches of less than five feet and areas where it cleared up really well- just under 20'.
Did a night dive down DT road- we just followed the lane lines out for a while- saw a good amount and variety of fish on the night dive. Vis wasn't too good, but seeing the fish made it worthwhile. Temp at depth was 57-54 degrees depending on the dive. All and all not too bad- despite the crazy amount of people! Makes me long for Scorpion bay...
