I don't know exactly whats been going on since I don't live in Nevada but rumor has it this track needs money to move or will be shut down! If I'm wrong or anyone has better word on what's going on feel free to correct me. Only reason I know this is happening is because Twitter has been blowing up with tweets about it!
