i live in Los Angeles Ca, and looking into taking Aikido classes. does anyone know if there is a Tenshin Aikido Dojo in Los Angeles? ive visited Honbu Dojo (Sensei Obata, Toshishiro), and LA city Aikido (Sensei Kazuho, Nishida). both looks good, however, the LA city Aikido has a pretty small dojo. And Hondu Dojo has a big Dojo. is their really a difference in Aikido techniques from different dojo's?
