I’ve tried. Once a prohibited state is placed in the address box during signup, all kinds of nasty things happen. No go for me. A few years back, while visiting Las Vegas, folks were pimping a device on which you could place bets on multiple events. It stops working at the state line - GPS controlled. Kinda slick.
I also just heard that some horse tracks are caving in to panic. This sucks.
Right now, the only major tracks running are two in Florida (Tampa Bay and Gulfstream) and Oaklawn in Arkansas.
Fonner Park in Nebraska is breaking tracks records in handle the past few racing days but that is usually early in the week.
Oklahoma has two tracks operating (Will Rogers and Remington) but I believe both are QH racing this time of year, same as Los Alamitos in California.
