I'd love to find a skilled instructor or study group with whom I could train on a regular basis, but given the (apparent) rarity of quality internal power instruction in the states I'm not optimistic about finding anyone in my area.
I know a few excellent aikido, taijiquan, and karate teachers in the DC Metro area. I'm not exactly sure what you
mean by "internal power" though. Feel free to PM, and I can PM you some training sites that I know about.
