I have a love/hate relationship with Costco. I love the prices and the high quality produce, but I hate the long lines. During the day, you have the stay-at-home moms with their kids crowd, and in the evenings you have the after work "let's pick up something" adults. There does not seem to be anytime when this particular Costco is not busy. Someone told me that this Gaithersburg Costco is the busiest Costco location in the country! I believe it. The best time that I have found to go is Friday evenings, right as it is about to close, around 7:30 pm-8:00 pm. Good Luck!
