Another Kozak? No way! I climb at Great Falls and Carderock quite frequently on weekends (Great Falls more than Carderock). I have a fairly sizable group of friends who climb there as well (girls included). We're all mid to late 20s and have been climbing for 2 years as well. We're a very welcoming group and would certainly be cool with you joining in. We also go to Sugarloaf Mountain frequently and my buddy and I do weekend trips to Seneca Rocks when the weather looks nice. Feel free to PM me if you're interested.
