Morning Bill
Working tracks here in the East like Ct, Pen, Mnr especially this time of year often leads to chaos. Off tracks, snow, wild fluctuations in surface(track) speeds and variants are the norm rather than the exception.
My feedback would be to stick with Santa Anita and the SoCal circuit where you had success. Then consider other Polytrack venues like Woodbine (scheduled to open tomorrow

) ,Turfway, Arlington.
Fwiw Woodbine has the longest running meet with the lowest % of favorites winning and one of the highest avg win prices in racing today. You will find good field sizes and better horses along with a super turf course and polytrack surface that is "done right". Attached are the stats for the WHOLE meet from last year and remember this runs April through December.
Best of luck Bill!
