Same here, Mrs. Alaska has "only" seven full sized trees up this year, but they will be up until Feb.
An old friend might not take down her tree until March or April. One year. Wife and I were going to visit her in late January and passed a fake tree on someone’s trash pile. I stripped off a handful of the plastic pine needles and while Amanda was in the Kitchen with my wife I distributed them on the floor under her “tree.” She didn’t notice until we were about to leave and said that was weird. Wife told her the “tree” was shedding its needles. She looked perplexed and denied that could be right but disposed of the thing the next day.
