On the 2nd year at Wakefield, our previous years licenses were still valid. Good value.
I would have expected the license to have a expiry date on it, not the start date. If it expires on 1/10 then you are sweet.
If it doesn't and as your post reads 1/10 is the start date...then I guess you will have to renew to be able to compete on the Sunday...shrug.
I didn't compete last year, so don't have a license handy to check.
