Arenacross: What happened?

With everyone focused on last weekends Supercross race in Phoenix, there was another series going on. The National Arenacross Series made stops in Baltimore Maryland and Dallas Texas. I'll never understand why Live Nation decided to start having two races in different locations on the same weekend, Also, what's up with the one night races? Some say that having two different location on the same weekends makes the points race tighter, and in a way they have a point. It can also help a rider that is down in the standings move up in the points. If it's one of the two venue weekends, as a rider looking to move up in the points standings can decide to race the round that has the least competition and he takes the win both nights, he can easily move up. But, then you have the argument that they're running away from the competition. It's catch 22. This whole two races at different arenas also brings me to another point. What in the world happened to Arenacross? Where's the Dash For Cash? What happened to racing both classes on both nights? Now I know with Arenacross being part of the new qualifying system for Supercross, and making a rider who plans on trying to get a "lites" license ride a 450 sounds a little odd, but come on that's Arenacross! That's what made it so great!
