What are the biggest slot car racing facilities in your region of the country/world in operation today? By biggest I mean a combination of most tracks plus most track footage. I guess six lane tracks should get only 75% of the credit of eight lane tracks while 1/32 scale plastic tracks should get only 75% as much credit as 1/24 scale tracks while HO tracks should get only 28% as much credit.
Here's my nominee for New England and perhaps all of the Northeast:
220' American Sovereign
155' King
135' American Aristocrat
90' American Royal
90' Ogilvie Figure Eight
84' HO Bowman Sovereign
HO Car Model Track
How about other regions?
