I admit I am no expert. I give up posting my opinion and leave it up to the experts to battle it out.I respect pretty much everything I read on this website.It doesn't mean that I agree with everything.I'll stick to the questions,Chris,but sometimes I feel imtimidated that its a stupid question.Since you are the reason that I decided to post when you asked more people to post that come here, I'll keep posting. gary, vermont, usa
