Going to the gym stopped at a lights smoking like crazy out of exhaust. Looked at the temp gauge topped out on the H. I panicking I turned off the engine. The at the light main street and 35 in Lewisville. I car won't start so pushed it with help into a parking lot. I think a heater hose popped when I was on the highway. Sad :-(. Really hope damage is minimal :-(. Might have caught it too late. Waiting for a ride and or tow. So who takes miata emergencies :-(
