Sounds like they'll have to drag him out kicking and screaming. Wallace wrote this on his blog on Tuesday:
"There is no retirement imminent for me. I've had to call the races with a broken wrist this year and it shocks some of the fans to see me call the races and walk around with a cast on my hand. But truthfully that has been no problem and I am just like so many of you--hating to see this come to an end. Oaklawn racing is such a wonderful experience. But for all of us who are older, everything moves faster. There is really an acceleration of life as you are on the downhill side.
Although I am not planning a retirement, I will be going on vacation to England and France for, among other things, the Prix de l'Arc de Triomphe in late September and early October. I've mentioned it before. People can join up with our group, if they choose. It's not cheap, but it's the trip of a lifetime. If you're interested, you still have time to contact me at Oaklawn to join the group."
