What if you had that large field every week at your club? It can happen and it used to be that way. When there wasn’t 30+ dates a year for national races you just raced at home and tracks nearby with a couple big nationals a year.
I know they have this at a few distant tracks we go to. It will be great if anything within 2 hrs of us returns to this, it would be much better than traveling like have to do now.
