[Rhodes22-list] Battteries

Bill, So you know better than the entire Golf industry? Maybe green fees 
could be lowered if they knew what you knew.....I got to believe the golf 
course industry has not been duped. I suspect they pay the extra bucks 
because there is a difference. In any case... I said in my orignal post for 
my use they are not worth the cost. Wally
