Your snowfalls are really "minimum" but - your area's are not supposed to have snow. Your road crews don't have the equipment to handle snow. Our roads are virtually clean throughout snowfalls, except for major snows - a foot or better. The road crews out here are AMAZING. When we first moved here, we woke up about 4:30 and saw flashing lights going by. Got up & it was the road crew getting the roads ready for the school bus.
Poor guys up North got hammered (Northern NY) Got several FEET last night. They missed out on most of the Dec snow, but sure making up for it now.
