When I pulled in on Monday, my bike radar immediately went off: Jon's bike was wearing studded tires. Of course I gave him the obligatory krap about his lawlessness, considering that studs are not legal on Washington roads until a month from now.
Yeah, it's a touch early - they're brand new and he's just breaking them in on dry pavement, like the manufacturer recommends. But still. Forget about squirrels and nuts. This is proof positive that winter is on its way.
