Sorry, Bay seniors, it’s too late to sign up for Golden Gate Park’s Turkey Trot but you have other choices. You might want to try the Nitro Turkey Run at Point Pinole in Richmond on Thanksgiving morn. There are both 5K and 10K events over a gently rolling course. Kids under 10 have their own race. It’s a park you should check out anyway with wide-screen views of the North Bay and historical reminders of the dynamite plant that was once here. Outlandish costumes are encouraged.
