I did some riding in Vegas last December. I stayed in a hotel just off the Strip, and tried to get out to Red Rocks a couple of times. The problems with Vegas:
1) too spread out - it takes forever to get anywhere
2) the traffic lights just take forever! You're waiting at the intersection for about two minutes before you get the green, then you get to the next stoplight one or two long blocks away, and it's another two minutes. There doesn't appear to be any synchronizatin for cars or bikes! I make it a rule to stop and wait at all red lights, but for Vegas I was very tempted to make an exception!
