TDA in Sacramento is where Klingon went to school... They will give you the info and such, but the trucks will be older in Sac, and their pretrip will have so many more words than what is required... If you are able to go to Fontana straight off, then you will be able to learn in the truck you will be tested in, on the roads you will be tested on... Thats what I was able to do... Just a thought...
Also if you have the $50ish then fly to Fontana... They will reimburse you the amount it would have been via bus, so you end up just paying the difference... And the experience is MUCH nicer!!
