I did the hillclimb "Come and Try Day" at the end of January but haven't done an officially timed run yet.
It looks like the deadline for entries is today. (04/05/16, May the Fourth be with you)
The MG Car Club always seemed to like to process entries by snail mail but there is now an online entry through CAMS.

Looks like I've just signed up and paid ($85) but I haven't received any separate confirmation yet other than when the credit card payment went through.
When setting up the meecamsau account it kept telling me my CAMS licence # either didn't exist or had expired.
I'll follow up with CAMS and the MGCCQ tomorrow.
Anyone else keen to make further use of their L2S licence?
There's got to be better/faster ambassadors for the MX5 club/community than me

Other clubs (potentially) competing:
Lotus, MG, Holden, Porsche, (Nissan) Z Cars, BMW, 86's, Alfa Romeo, MR2, Triumph.
Personally, I'm hoping that this is a semi-quiet day where I can gain some hillclimb experience with smaller crowds than the Hillclimb Series rounds proper.
It is however listed as the last chance for track time prior to the Qld Hillclimb Championships on 4th/5th June.
