Hi, Vaughn:<br /><br />Are you an economics teacher, by any chance? This is excellent stuff! Please let me know which airline you're investing in. I'll buy shares in the same one.<br /><br />I've made a few changes for flow&nbsp;but didn't touch the content. This is your most impressive submission to date. If this goes on, I'll have to read up on economics. (I subscribe&nbsp;to The Economist. Does that count?)<br /><br />BFN (Bye for now) - George<br /><br />&nbsp;
