Sturgeon Stampede is according this website http://www.eventcrazy.com/Fond-du-Lac-WI/events/details/238687-Sturgeon-Stampede The 2nd weekend of February 2012. I am keeping a spot open in my agenda to visit this crazynes. After seeing the video from last years looks like a great place to be!
Second one my personal event:

The idea of King of Grasslake is to have a great day, swap gear, hang on new gear, do some jumps and enjoy. Grass lake might not have the best ever snow conditions but for me, and probably many others last season, was a lot of fun out there. I am building a small ramp that will be small enough and portable to haul with me to grass lake for the crazy jumping people (or just who wants to try it for once).
People who want to participate in making this day in something that might can come back every year please drop me a PM or send me an email.
Please share idea's about this, the event is more a get together then a competitive event. We'll see how it will turn out this year. I don't want to set a date yet because I dont wanna interfere with the Stampede and other events that might happen this winter. I was planning around February or beginning of March.
Please fire off idea's. Don't stay in your comfy zone and "just read" what the people are doing bring out your idea's as well and like I said before maybe we can turn this in to something yearly!
Looking forward to your comments
