The Large Woodlot is arguably one of the BEST ways you can spend your hard-earned Rubies! Lumber is one of the most needed resources and I was constantly scrounging for it, until I purchased my first Large Woodlot - that changed the whole game for me! Purchase it, run it as often as possible and soon you will have thousands and thousands of lumber too!! (That is not an exaggeration!)
The large Woodlot acts as a level 3 woodlot for any quests.
