Actually, I volunteered for 10.5 hours and walked 13.5 miles while there

. I was a greeter and took people to wherever they wanted to go first and then showed them where their next stop would be. It was very fun! As a volunteer, I was able to get two items appraised.
I took my Willie Mays skateboard. Grant from MBA Auctions in Seattle said $1000 and from what I've seen, that's about right (even in this condition). I recently learned these were made for one year only, only sold in CA and only sold at Macys.
My other item was this 9' wide bunting. Thanks to Dave Grob (I think), I was able to photo match it to the first Opening Day at Candlestick in 1960. Grant liked it and said $1500-2500
