Hi Charles,I had been using SF for over a year prior to attending the class and I still found it to be extremely beneficial. My two coworkers who also attended and are new to SF have said that the training will really help them in getting up to speed quickly. Not only is the class well thought out and all inclusive and the instructors excellent, I really enjoyed talking to other SF users to hear how they are using the product.
While August would not be my ideal time to visit Amarillo, the A/C does work very well and if you ask nicely, Trent may take you out for a beer.
