Sigh

So,  tomorrow's adventure is taking the bus to and from work. My car heater is blowing cold air, but the engine is running all the way hot. Noticed the latter on the way home from the grocery store tonight,  and prayed I'd get through the half-mile or so. I'm not 100%, but I think that might mean getting a new thermostat. I have a regular mechanic I trust,  but they're only open weekdays. Any recommendations for a good weekend mechanic?  I think I may call mine (Kenny at Mitch's Auto, excellent folks) to see if he knows anyone. With the new job,  I accrue vacation and holiday time,  but can only use it for holidays at first. So weekends would be preferable.
