Santa Claus cruised Lake Washington Wednesday morning - via water skis - to benefit charity. A group of local businessmen took their first spin around the lake in Santa suits 20 years ago and decided to try it again this week. While this particular Santa took a spill, the event to benefit Seattle's Ronald McDonald House no doubt entertained I-90 and 520 commuters. Ronald McDonald House provides support and housing for out of town families who need to be in Seattle so their child can receive medical care.
