Dale, I would consider attending but it's pretty pricy for a four-day lark (especially in the current economic environment). If one attends all the special luncheons, dinners, receptions, etc., in addition to be basic conference that's about $500, plus $600 for four nights at the hotel, and airfare, and miscellaneous expenses. That's a lot of money. Does the NSS get much of a turnout for these things? In future years you might consider holding this at a less expensive hotel (does it really need to be in Orlando?), and more reasonable pricing on all the "extras" ($45 for a lunch?); you might get more participation. Just a suggestion. I hope it goes well and you have a good time.
I read that Branson is talking about planes soon taking just 3 hours to go from London to Sydney. Some people might pay for the initial voyage, as a near-space experience, but at $200,000 a ticket, I'll stick to Jumboes!
