dbf, your posts have been among the highlights of this thread for me. I have actually learned something useful from them. It is clear Roscoe is just a wind up merchant. If he had anything valid to say he would have said it by now. Please do not waste any more time on this fool. Your contributions and effort can be much better spent elsewhere than in this soon to be closed thread. Roscoe, can you link me to your schedule of lectures please? I'm always happy to see money going to a good cause like the legion.
