To all those interested in the art of concrete: STOP. Put down the bag of concrete or the book from the library or the trowel and contact CCI. This is the most comprehensive class you will find. The facilities and accommodations are absolutely first rate. The knowledge you get from CCI will prevent years of frustration. The complexities of this art form are entirely too intense and numerous for a trial and error system. Just bite the bullet and enroll in a class now.
