What are the requirements to qualify for the series - is it just doing the two days in Calgary and one day in Red Deer?
I can answer this one in a general sense. The intent of the regional series is to get you outside of your usual "haunts", so you will almost certainly be required to attend two events outside the province. So, you will need to attend an event in Saskatchewan and Winnipeg.
I haven't attended an event at the 3 flags venue in Sask yet, but I want to. Supposedly smooth and extremely grippy surface. The Winnipeg venue is an old airport with a very bumpy surface, but the people and course designs are exquisite. Make this a bucket list item -- I don't think you will be disappointed.
And after that, start thinking about expeditions to other venues and clubs. I can wholeheartedly recommend Great Falls, Helena, Vancouver, and Packwood, all within a day (or two) drive. You really aren't doing the sport justice until you start competing against people and clubs "from away".
