Looks like we got our extra biomass cleared out just in time. It was raining this morning–for the first time in weeks–but stopped by lunchtime. Got to love Seattle. Yesterday when we were watching the Mariners game, it started raining in about the second or third inning. I learned two things: (a) the roof on Safeco Field takes about four or five batters, depending, to move over the entire field; (b) Labor Day really does mark the end of summer, in a very real way, in Seattle. They’re calling for intermittent showers all the rest of this week…
