You don't have to be a URG member to attend. Everyone is invited.
Folks, everyone who has been to this conference says it is the best one available. They have 4-5 seminars PER HOUR for 2 days. If you have never been you should consider adding this experience to your training schedule for 2008. I have never heard anyone say it was a bad experience. Almost all of the seminars are lead by other recyclers.
Also, if you like to ski you can come early or stay late and spring ski in the Rock Mountains.
Some of the best skiing in the world is available within 1-2 hours of Denver.
