1) How do your child's sensory needs color their response to cold weather?
Jake does not seem to notice hot or cold, generally speaking. If the covers fall off he curls into a ball. If he's hot in the summer he falls asleep next to his window on the floor. He loves the outdoors more than he dislikes the elements, and would happily play in our backyard well past the time a "typical" child would seek warmth. (This is a picture of Jake in our backyard in a little fish pond we no longer have because he would get into it whenever he had the chance no matter how cold it was outside.)
Because we have to be aware for him we try our best to clothe him in the most appropriate outfit for the cold. I try to wear a similar number of layers and fleece/wool combination so I can help gauge when he might be too hot or too cold. We spend hundreds of dollars each year to get him the new size of snow overalls (bibs), snow boots and gloves. Of all the children in the (extended) family, it is most important to get Jake's outfit right, since it seems to make or break any snow event for the rest of us.
If Jake is not comfortable he will whine or drop to the ground repeatedly until we remove him from the situation or correctly diagnosis his need. Once we figure out the problem, he will generally have a little more patience for us to fix the problem, but if we don't he lets us know he's done.
2) Can you relate a particularly memorable, related incident?'
My family loves to ice
3) Have you had to modify your family's routine or lifestyle (or location) because of your child's response to cold weather?

Descartes and I made a plan several years ago to move to Tahoe. We love it there: supportive family, beautiful scenery, reasonable cost of living (compared to the Bay Area). We researched available businesses for sale, did due diligence on a sporting/outfitters store and began looking into financing. We started talking about selling the house.. the whole deal. We went to Tahoe on a Friday night, giddy with our plans, sipping wine and laughing with my sister and brother in law about the great life we would have. In the morning, after a fresh snowfall we went to play in the backyard. We bundled our tiny new baby in a bunting and set her on the snow. All wrapped up she giggled and watched as her brother ran around the yard. Watched as he flailed and tore off his hat, and his gloves and hopped out of his boots. We got his boots back on, eventually. We ended up duct taping his gloves onto his jacket with his hands sort of stuck in them. I'm not sure he has ever worn a hat since that day 3 years ago.
When the gloves came off again we were done with the whole thing. Exhausted, we stripped Jake down inside the house and realized that we could never live in a climate any less temperate than the Bay Area. Overnight lows in the 30's perhaps, but winter days in the teens? Though the benefits of family support were so tempting, the idea of epic struggles every single day just to stay safe was just too daunting. If not winter and gloves there would be summer and sunglasses. Tahoe kids wear gloves half the year, and things like hats and sunglasses year round.
We were very sad. It is hard for us to admit defeat; we make plans and we execute them. We don't know what our family would be like without autism so we just keep plowing on making choices and dancing through this life, and most of the time we are happy and strong, but sometimes we are stopped. Of course we could make it work, living in a place with "real" seasons, but would that be fair to Jake, being tortured daily for months on end? Would it be fair to his younger sister to have to wait 20 more minutes each day while we get her brother dressed, the little girl who already has to "wait", "hold on!" and "be patient" constantly?
We still play in the snow, but this New Year's day we
