This morning I woke up and was wondering if it would have been too cold for kiting...

let's go and see it!
I got to Lake St around noon and it looked like this:

I rigged my 6m on short lines and 50% depower: it was perfect! We rode for less than half an hour then Dewsy left and I decided to call it for the day because the conditions were not "ideal" for a solo session.
When I was about to leave but still with my wetsuit on John Strapless showed up (sorry, I don't know your name on the forum) and I decided to go back in the water but by the time we got ready it started nuking above 40, snowing a little and getting colder quick...fu&#!
This winter is giving a lot to the kiting community this year, thanks!
