Like the flip of a switch, spring blew into the Twin Cities this past week.  Last Monday, May 1st, brought us snow flurries in abundance – it looked and felt more like November than May.  But as the week wore on, the temperatures rebounded, the sun appeared, and the leaves started opening.  The tulips and daffodils became riots of color, the crabapple trees were awash in pinks and whites, and the once-barren, brown grass became green again.  This weekend found people outside – gardening, walking, running, biking, having parties on their patios and decks – anything to soak up the warmth and the return of spring.
