Success can be found in the most unexpected places. Like Walgreen's.
Allow me to explain. Many conference attendees, including me, were caught off guard by the cold and windy front that swept into SF on Sunday and Monday. (The high temperature Monday was 54 degrees. Without the windchill.) I saw several ENDO-badged brethren wandering the floors of the department stores near the convention center looking for warm clothes as they (and I) shivered in lightweight suits. Personally, after going to six stores, I could find only a gold hooded sweatshirt suitable for a 13-year-old, and a winter coat "on sale" for $300 at Macy's.
Then, on a side trip to Walgreen's for toothpaste, I hit upon a bonanza of toasty, affordable sweatshirts and jackets for tourists.
So if you someday find yourself at a conference in SF having a Mark Twain moment (he's the one who said his coldest winter was a summer in SF), you now know where to go to warm up. As long as you don't mind wearing a Giants jacket in front of your colleagues.
