ok, so we're gonna take Alex's advice and just shut up and go.
Despite that there's apparently a bewildering variety of tire sizes to which snow chains or cables must be fitted, we're going to trust to our assumption that towns and villages closer to the mountains will have some variety of the stuff, even in MID-FREAKING-APRIL ... otherwheres known as idyllic Springtime.
If we don't find any and they don't let us in the Park, will someone come down to El Portal and get us??
