last time my grandaughter came along to a game with me, the franchisers were still accepting cash at the concourse kiosk under SSL ( fence end) - which is closed today ( not a lot of help I guess @oufc1991 ?)
I use the hand warmer versions inside my gloves and they’re brilliant, toastie hot! Just ordered a big box full to get me through the Kasstad winter.
Just unwrap 5 mins before you use and I find it helps to expose them to the cold for a few mins to speed them up.
