I bury my spent grains in the back yard while the boil is rolling.
Usually I start my brew day at 9 or 9:30 AM so I don't have a beer until after noon, but like Denny sometimes you have an event away from home where people are constantly giving you beers starting early in the day. I guess the more people spectating the more likely you'll either make a mistake or have somebody tell you you're about to make a mistake. Some of my best and worst beers have come from these events.
