boy - I don't really deserve to get this one!!
well, the only other 1 mile track on the schedule that year was Milwaukee (I was thinking Trenton was more like Pocono - but it was a mile and a half....)
I guess one of these days I am going to have to wander up to Trenton to vist the NJ State sculpture garden and see if there is any sign that it was once a race track.....
