I climb at Earth Treks Columbia twice a week. I have been wanting to organize a climbing trip for HN folks to introduce people who are new and meet people who already climb, and now that I know there are at least some of us @ HN, this is more and more a possibility.
Cool. Let me know if anything gets organized. My friends and I frequent ET, but I mainly goto the Rockville one. I also work part-time at a very small climbing in Rockville (2 out of the 4 hrs its open a week).
edit: thanks for the link!
