I would say join one too.
There are always new teams that start up, but with new teams there is a problem lacking commitment turning up to training and not being able to make events.
Teams that are established have a general understanding to what they expect from their player base. You will learn about running a team and how a team is run.
Running a team is a massive undertaking, you will lose time and money BUT the rewards can be fantastic
BZ have a team and i believe they are always keen help you become a better player. I think they still train in Dishforth, you'll most likely need a car to get there unless if you can find or arrange someone to give you a lift.
If you're interested heres the guy you shuold get in touch with, he runs BZ supplies and also runs the team;
