Trying to describe going to a baseball game in June or July at Candlestick? Imagine sitting for three-plus hours inside a walk-in freezer turned to its lowest setting with industrial strength fans blowing at maximum speed. While keeping score and having hot dog wrappers randomly hitting you in the face.
For a DAY game, you'd have to pack the same clothes you'd wear in January to ski at Lake Tahoe (15 minutes away). The difference in temperature from Contra Costa County 30 miles inland from the 'Stick might be as much as 50 degrees some times, not counting the ever-present fog bank and the wind. Walnut Creek - 99, South San Francisco - 49.
Oh, and how the wind swirled in that dark, dingy concrete toilet bowl of a stadium. There wasn't one seat I ever found where you wouldn't be subjected to it, not even the press box. Upper deck. Lower deck. Third base side. First base side. The Green Bay-Dallas Ice Bowl was "shorts weather" compared to a Giants night game that went extra innings. And yet, September and October can be glorious weather there because the wind and fog retreat in the fall.
And I was told it was even worse before they brought the fences in and bowled in the left field stands.
(Not to mention Hunter's Point was the worst neighborhood in The City. Not a great place to have car trouble after the game. And getting from the Bay Bridge to the Embarcadero Freeway there, not fun. Especially going the other way in rush hour traffic.)
