Here's my short story on how I got free parking for Game 3 of the SCF and Game 3 of the WCF.
I usually park on Olympic and Grand. Ranges anywhere from $4-$7. For Game 3 of the Conference Finals, they shot up to $15. I thought that was too much, so I drove further down to Grand and 12th. That's my backup lot, normally $5-$7 bucks. Strangely enough, there were no parking attendants or price signs. We all parked there, looked everywhere for someone or something to pay but no luck. We all thought, "Screw it, lets try to enjoy the game and worry about paying later." After the game, still no one. We all parked for free.
Game 4, I took the Metro because of the bike tour stuff.
TONIGHT, went to my usual lot on Olympic and Grand. $15 bucks again. Went further down to Grand and 11th... $25 bucks. Went back to my backup lot on Grand and 12th. AGAIN, no parking attendant but the lot was full. I think everyone knew of the free lot there. So I turned left on Olive and made my way back towards Grand, the lot there was $10 and it was all full. The parking attendant told me to go across the street (Olympic and Olive) for $5. That lot ended up being full too!
However, the one right next to it at Olympic and Hill had a TON of empty spots. I was with about 4-5 other Kings fans trying to pay for parking but the guy said that wasn't his lot and he didn't want to take our money. He told us that they had parking attendants there earlier in the day but they went home already. He said they've been doing that for awhile and that we can park for free there with no worries.
So I'm definitely trying that lot again on Wednesday and see how it goes. But I'm just saying... if ya want free parking during the FINALS.... this is it.

In case you were wondering, I got to the lots at around 4 PM today. It's only about a 4-5 block walk. Took me around 10 minutes (then again, I walk fast).
