Narrative:

I was distracted by an outside object; a balloon (maybe); a potential flight risk/ hazard. Near north end and slightly west of lake sammamish. I exceed the floor of seattle's class bravo airspace by about 300 ft. Or so; the floor is 3;000 ft. After clearing potential conflict; I descended to a suitable altitude below seattle's class bravo airspace.
