I own my home and am as happy as I can be at my current job, why would I decide to move 350km away where I would have a rent/mortgage, need to find new work for my spouse and I, and live in a city that literally reeks of sewage constantly?
As for "planning better", cold snaps can happen at any time from late October to early April around here, and if one happens when I plan to do some shopping for necessities where its 20%+ cheaper? Oh well, at least the roads will be more likely to be clear.
