i know exactly what you mean
So to first say, I had a good teacher but at the same time it was a buddy who didn't explain maybe what he thought was obvious? It took me the better part of the day to figure out I had to use edges. anyway, that being said after that I was going down blues no problem. That is the hardest I have done so far but I learn fast once I get a system so next time I go I am sure I will see how a couple blacks go.
As for that feeling when you get home, I had it for like a month. I would close my eyes and be going down my favorite blue. It subsided for a while and now it is back and I am desperate for some snow and a board, never been this obsessed with anything before. Right now I am trying to get clothes and gear that I can't rent before the season starts. Not sure if I will buy a board/bindings/boots yet as that is a much bigger investment
