The closes school apart from this one is 1 hour and a half by car
Closest school in the same group? Because...
I had to stop Judo and Karate due to me moving to the UK
So you're in the UK...
I'm in the UK, out in the countryside.
Within an hour and a half drive I would be shocked if I couldn't find an absolute minimum of 200 martial art schools, a good proportion of which would be judo and karate (of various sub types).
Just in my local town I can point at 3 tkd, 1 judo, 2 karate, 2 kickboxing, 1 western boxing, 2 aikido, 2 MMA, 1 KM and 2 WC derivative schools - and that's without going back to Google to have another look. And that's less than a 20 minute drive to a not very big town. Going for an hour and a half gives me at least 10 fairly major towns and cities. Oh, and like a third of London if the traffic is relatively clear.
So yeah, y'know, not much choice about is there...
