I saw this at Obe's track archives( http://roadrage.sports-gaming.com/upload/ )and had to see what it was.
I must say this is the longest, tightest and funnest arena based MX ive seen. Great idea and great work joining 3 arenas (like torture pit).My major description of this MX would be long twisting two level arena circuit. I love this track and would reccomend you download it to see ONAN's great work!
