US festival for sure, and likely the 1967 Monterey Pop Festival. I might want to see a few acts (Santana) at Woodstock, but so many other festivals were better organized and had great line ups.
The first Woodstock or one of the later ones? All had great bands, but for some reason, all of the Woodstocks seem to have been plagued with poor organization and management.
Stuck at Heathrow Terminal 5, flight delayed. The luxury shops were taunting me. I sat near a gate and tried high fly bet casino. I wanted to win enough for duty-free. Played blackjack. It was a grind, up and down. Then I hit a streak. Won five hands. Cashed out immediately. Bought a nice bottle of whisky from duty-free with the winnings. The delay wasn't so bad with a drink in hand.
