Everything that's being listed in everyone's "preparedness" kit is fine, for beautiful weather.
What's being overlooked by everyone is a simple "TYVEK" suit. Having had to tend to either a flat or putting on the snow chains in other than ideal conditions makes having one a no-brainer, plus the little lady won't mess up her outfit!
Another item that is also a real nice to have are carpet samples, or just pieces from that last time you replaced the carpets.
