I've been there a couple of times, and enjoyed myself, met Sensei Ray Munn(?) once. But it's a fourth night a week training and I can rarely make it.
The offer is open the other way, your welcome to join us in Dunstable or Dinton, outside Aylesbury. Both of the Sensei's (Antony Pinchbeck and Jeremy Osbourne) travel overseas a couple of times a year to train with Endo Sensei, and many more times to train with his students. (We were in Norway last week with three teachers from Norway, Sweden and Germany!)
So if you enjoy the style of Aikido Endo Sensei teaches please come and see us.
(Email me if you want further details or directions)
