Tracy, dont you love it when a groove comes together? The customer smiles and cant believe his or her eyes. The funniest one is when they say "thats all you did your done,"then they drive it and they come back and say "wow", then I say wasnt that enough,They laugh and say oh yeah I cant believe it!!!!!!! Such a little groove makes a big difference!!!!!!!!!!!!!!!!!!!! Dan gadgetman Mo. Happy Grooving
