Years ago I had a dream taking part in WWDC. Initially money was the blocker (as indie dev I had to pay everything out of my pocket, and 7d roundtrip to San Francisko from Latvia is really not cheap). Then it was challange of winning the lottery. But now traveling to US? Even if someone gave me free invitation and paid everything I would still stay home. It's incredible how Republicans fucked up brand of the "Land of the free" in such a short time. Probably for decades.
