Went to ESTC grounds today to have a look. The weather was wet and there was lots of mud, but it didn't seem to put anyone off, lots of people there. Spoke to the club secretary to figure out how to join so will get that sorted this week.
I also bought and collected a bike yesterday, a 2000 Beta Rev3 250cc. It's in very good condition for the age, but I'll run over it and do some basic maintenance, mostly changing all the fluids and the spark plug, so that I'm sure things are in order before I start using it.
Thanks for the details on ESTC, guys, it was just what I was looking for
