We started out from Gold Coast following our usual route, north on Dean Martin/Industrial and ran in to stop and go traffic between Stardust and Circus Circus, all roads going east to Las Vegas Blvd were blocked off. (No way to get to Maryland Pkwy even once we were downtown,i.e. you could not go east of LV Blvd or north of Fremont). When on Industrial, just past Sahara, we stopped to ask a cop WTF was going on. He explained the situation and suggested going east once we hit Charleston to M. L. King. Tried that but MLK was blocked off north of Bonneville (before Bonanza), so we could not go East on Bonanza and South on Main St. to MSS. Similarly, Grand Central Pkwy was blocked off north of Bonneville, so we could not take it down to Ogden and Main St. Once downtown, at Main and Carson, we backtracked, south on Main to Bonneville, west on Bonneville to Grand Central Pkw, south on Grand Central to I15, north on I15 to I151, east on I151 to Casino Center exit. Then I was north of Fremont and west of LV Blvd and could easily get to MSS. More detail than needed but it just illustrates how confused the traffic situation was that night. We even ran in to residents who could not get to their destination.
