It's the May long weekend! A kick-off to the start of the warmer weather (hopefully!), and the traditional weekend to plant your garden, as the frost dates have all passed. There's also barbecues, beer, and often, fireworks. Someone was setting off some last night, as the sky had cleared up a bit from all the rain we had been having, but soon after, there was a huge downpour, so no more fireworks. Oops!
