I just run a simple spreadsheet and put together a list for each trip. I start building it as soon as I shut things down for the winter. Prioritize what is time sensitive (planting, pruning), and what can be done when nothing else can (mud season, pre-plant time). Add to it, subtract from it, and then execute. First trip will be some late winter sun harvesting, trail clearing, scouting, cabin opening, garage cleaning, and cabin improvements.
