I remember I think it was June 8-10th 2000ish driving to Ellensburg to my best friends college graduation and it was snowing like gangbusters on Snoqualmie Pass, unexpectedly, and my windshield wiper motor died that sucked lol, but it was also snowing going through Cle Elum when I finally was able to see enough to drive slowly down the other side, very cool to see in June.
