We got a hotseat club started here in Memphis back in the mid 90's (about a year or so after SP was officially released) by putting up 3x5 cards out at the local military base (Millington) PX. Not sure what is still left in L.A. as far as military bases. You also might want to check local model or hobby shops. Guys that like to build plastic tanks have at least some interest in MBT's and might have an interest in Combined Arms tactics. Then there is the Math and Chess club at the local University. If you want a really out-of-the -box idea, try going to the public library and putting your 3x5 cards in books on tactics. IIRC that would be the 900 section, if they still use the Dewey system. 934, I think.
Some of the WinSpWW2 scenarios look to be well done enough to be use as history tutorials.
