Remember the old UHL?
Races were 3 or 4 weeks apart, Saturday mornings at 9am Pacific. Some years, there was a Vintage season in between the Modern races.
Real or Custom boats (no custom boats in Vintage)
In the season standings, you could drop your worst race.
The fun thing about Vintage was that we had Nitrous engine boost. You could go fast, but use it too much and Kablooie!
I remember :)
