I think it's a good idea to have the prior ones under their own category (SpeedWeeks 1949 thru 2019?) and have a separate category for the current one, easily accessible to novices and our elders (me!).
And I think it would be a good idea not to "lock" them. That would not allow new comments like "I met this strange fellow in 2003 at a combination tire-taco-gas station place that year. He's a lot smarter than he looks." Or "that was a great year ? for flat bottoms."
