Pro tech Smog Center opens at 8 am, which is pretty handy. Their location was easy to find, being very close to the intersection of El Dorado and Alpine. Alan helped me this morning and was very polite and personable. The waiting area was clean, with lots of seating, a television and magazines. It cost me 48$ for a smog test certificate and transmission to the DMV. I will definitely be coming back next month when my other car comes up for registration.
