There is more than mere nostalgia at stake. An entire generation of children is being taught to ice-skate USING WALKERS, a trend that threatens to ruin skating forever. Are children more fragile than ever before? Has the pathetic little ice rink at Seattle Center been expanded to accommodate these new six-legged wuss-monsters? NO. Those of us on the side of right and the side of sense must go and do something. Make a scene. Take away a walker. Do whatever you must. (Fisher Pavilion, Seattle Center, 684-7200. 11 am–10 pm, $5 adult/$3 child plus $2 skate rental.)
