Sleighing, while it sounds like a lot of fun, requires more than one might think! As mentioned, pretty specific snow conditions are needed, for both ease AND safety, and, you sort of have to learn a 'different' approach to maneuvering...runners do NOT handle like wheels; you can turn over in a heartbeat!
I have driven my Frontier on snow here, under 'good' conditions...meaning firm ground underneath not-very-deep snow, or snow that has been packed, but not made icy, by autos. Frontier makes 'runners' you can buy to change off with the wheels, but a 'heads-up',years ago, from the gal I ordered my first Frontier through, about how flimsy and unstable they were, turned me off the idea of buying them. I DO tie my little string of 5 antique cast brass sleigh bells(what a wonderful tone they have!)onto the harness saddle when I drive in the snow, or around holiday time--sounds very festive!
Did you know that the saying, "I'll be there with bells on", came from the days of the huge Conestoga freight wagons? It was common practice for there to be bells, with a distinctive tone for each wagon, on one of the team; it helped notify others on the usually-not-so-great 'roads' of the time of a wagon's approach, allowed them to 'plan' on how they might pass upom meeting (Conestogas were HUGE things!), etc. If a rider(there wasn't a driver, but instead, a person riding 'postillon' on the left wheeler, to direct the team) had problems and had to have the help of another wagon 'rider', he customarily was to relinquish his bells to the one who'd helped him. Hence, if he then arrived at his destination w/o his bells, he was seen as one who hadn't been able to 'make it' on his own...so 'being there with bells on' came to mean 'I made it by myself', needed no help!
Google Conestoga wagons for some fascinating info on these mammoth vehicles! They are NOT the same thing as the 'family' wagon, or 'Prairie Schooner', often seen in movies about the 'old west'...about the only thing they had in common was the canvas-over-bows top!!
