Hello Jerry welcome to the strike point. There are several books on the market. You can go to www.artbecker.com he has a book, a cd rom and a program for a pda. Also I believe you can get a copy of Richard Anderson's guide from Lisa Jung at http://chipermel.lvha.net. There are several more maybe someone else will chip in more info. If you are not a member of CC & GTCC or the silver strikers chapter you should look into joining up. There are over 500 members chasing the silver strikes and most like to trade.
