Welcome to the forum and congrats on the new bike!
Sometimes you can get into the MSF classes more quickly by either a) getting on a wait-list or b) just showing up every week until they have a no-show. If you take option b) be sure to have cash in hand for the fee.
I’ll leave the others to lecture you on the evils of learning to ride your bike on your own – even with lots of extra research and precaution on the side.
Post up some pics of the new bike!
