If you don't already have plans for Memorial Weekend, and you have the time/money to get to Denver, and are interested in space, you might want to consider attending the International Space Development Conference, sponsored by the National Space Society. I've been to many of these, and you'll find programming to suit every taste, from whiz-bang technologies, to recent results in space science, space law, and discussions of asteroid mining, colonization and settlement. It's probably the largest gathering of space enthusiasts you'll find during the year.

Don't miss it if you want to find out the latest in our progress to spread life into the universe.
