LOL, Frosty, that maybe true, but to quote my math(math for non math major 101) prof, a calculator is the greatest mathmatical adavancement, but it is useless unless you know how to get where yer going(with your calculations) with out it, but I have yet to get *bad* information from anyone here yet although I always try to verify any ideas or at least apply my own "backyard engineer" knowlege of what doesnt work and what wont get me hurt or burn down the ranch... It all goes to the give a man a fish/teach him to fish thing. Besides you got to have somekinda brain, you landed in AK. ;)
