So for the last week I have been preparing to train on approach for Portland, which is Class C airspace. I have mostly been working Class D airspace around the Seattle Class B airspace. That has some challenges to include VFR inside the class B, the traffic pattern at the airport I was at is 2500 and the class B starts at 3000. I can't wait to move to approach. Also to get ready for this move I have been flying VFR around the Portland area. LOL the ground Controller at KPDX gave me the wroking taxi instructions and I ended up at the ANG base there. It was funny.
