Which Parking lots are the Non reserved?
 

is parking lot A, still a cash parking lot and if not which ones are.

Clarion across the Freeway $10. coupon for $5 at hotel
bar/gift shop

The ones with dirt and grass.

Do they let you pay for parking there? If I didn't need all of my goodies for tailgating, I would definitely consider parking there.

is there any cement parking for cash parking?

Yes. They're the lots further away from the stadium. Lot N comes to mind.

West behind hotel lot. $10.

It's Perfect (for me). Get a beer at the bar before/after game or use gift shop....
(coupon valid only on game day)

I always bring 6 pack in plastic bag with ice. more than enough before game time. No muss no fuss.

Make sure you have all you need. Walk across bridge avoid traffic.

sobering walk back after while everyone sits in traffic.

Go out the back way thru neighborhood East or get on Freeway west after traffic clears.
