I'll be driving home from skiing while the @denver-broncos.bsky.social are playing Saturday. I don't get consistent cell signal through the mountains so radio is my best bet, but I don't know which radio stations carry the game. What a perfect use case to make AI look it up!

Just tried to pay for a large purchase with tap to pay on my smartwatch. Declined. Used the same card from my wallet and the transaction went through. The smartwatch is multifactor auth (something you have, something you know (to unlock it)) while the card is only single factor auth.
