Just sent an email. Might be worth a few more....

Hi Krista,

What an awesome day yesterday!! Would you please be so kind as to pass on the collective thanks of all the bike riders for allowing us to run on the GP circuit. We know there was some extra work for the flaggies etc moving witches hats around, and we all really really really really appreciated it!! It was fantastic that you all went out of your way to accommodate us bikes, and we are very grateful. We really feel loved by ARDC these days

I hope you have a great weekend!

Cheers,
Nick
