Rain! Oh glorious rain, how I've missed you!
Each year I always wonder if I'll ever say that again, but after suffering through a long, cold, icy and snowy winter, it's lovely to see some precipitation that doesn't put my extremities at risk!
If the rain gets you down, there are plenty of ways to keep dry. Blankets will quickly get wet and soaked through, but an old tarp will keep you dry all day! I use a shower curtain I found on the curb outside the Y.
Unfortunately most old umbrellas you find are in poor shape, so to keep your head warm and dry simply find or make a wide-brim hat. A bucket with holes punched in will work in a pinch!
