A selection of martial arts photography from events I have attended is hosted at Inner Capture.
Yin Cheng Gong Fa North America, led by Zhang Yun laoshi, preserves traditional methods of Bagua, Xingyi, and Taiji in the lineage of the late Grandmaster Wang Peisheng. This is the line of practice of internal martial arts I am part of.
I learned aspects of Jikishinkage-ryū kenjutsu at the Hōbyōkan, founded by David Hall. Some information on that art, including details about a book I wrote, "The Truth of the Calm Spirit: The Practice of Shinkage-ryū Heihō as Taoist Internal Alchemy" can be found at jikishinkageryu.org. That site also contains some information on active training groups in the US and Japan.
