I'm gonna have to disagree with you Tom, McDojo's waste your money and time and give you bad habits that require more money, time and effort to remove. I do not tell people lightly to buy "Kill or Get Killed" and work from the text. I had some friends some years ago who were planning to join a rather large McDojo in the Detroit area, one that I knew well from some other friends of mine who were ripped off by those charlatans. Unfortunately there was little alternative at the time for them, so I told them I would train them but it would take some time before I could do so as I had numerous other commitments. I told them to get KoGK and practice until I could get the free time (Honestly, I did it mostly to keep them occupied until I could get free). I was amazed when, almost three months later I managed to pry out enough time to get training with them, I had very little to teach them! All I had to do was help them refine their techniques and give them pointers on training for scenarios. After two months working with them (one day a week for 2 or 3 hours a day, they worked a couple days a week together as well) they were good enough to make me work to take them down and by the end I had to use advanced techniques to do it at all (can't let the young pup's get to cocky don't ya know).
Self training, alone or with your buddies, out of a book is not the best way to handle things, just as going to the range with your buddies is no substitute for good shooting school training. However it is better than having some schmuck take your money to teach you the crap he learned when he studied with Steven Seagal at his local VCR. Learn as, how and what you can and work to improve over time. If you and your bud's can't afford to go to a good school, pool your money and send the best teacher among your group and have him come back and teach the rest. Go down to the local VFW or AL and get to know some of the old guys there. One of the people who taught me when I was young, was a friend of my dad's from the 82nd Airborne Assn. who was OSS in WWII, he was old and not the best physically but he imparted priceless lessons and training to one young teenager. Just because a guy doesn't wear funny cloths and call himself Sifu does not mean he has nothing to teach. Resources are all around us, we just have to recognize and use them.
P.S. No I didn't rough up the guys I trained just to show how big and bad I was. I only used advanced stuff to show it was out there and (as much as I could) how to deal with some of it. I will admit though, I sometimes needed the ego boost, those guys got pretty good.
