My fort Stabcaves has just entered it's fiftieth year with an FPS still running high in the 30s. Its a simple fort, ten layers of stores, quarters, tombs, shops, and barracks underground, and a five layer castle complete with moat and towers and houses above ground. My clan dwarves (all from the same family clans) live underground, the rest above ground. Each group has their own tavern, food stores, and temple. Everything has run smooth this way for over thirty years (took twenty or so years to build).
But there is a problem. Stabcaves is prone to buzzard invansions every year. It becomes a slaughterhouse as surface dwarves pummel them in the bar, marksdwarves shoot at them from the walls, and food from the above ground stores gets dropped on top of the castle roof. After thirty years, my surface fortress is a mess. Broken crossbow bolts everywhere, blood everywhere, crossbow bolts and buzzard bits stuck on rooftops and fortifications. Even my well collapsed and the chain stuck in the cistern. And of course, the vomit. Visiting merchants must be totally disgusted entering the gates of Stabcaves. Strange they freak out at the site of one goblin tooth on the ground and not the vast quantities of blood... As for the bar... it must be the worst dive ever. True it has gold tables, but how much blood, vomit, puss, and buzzard bits can a person take before their mushroom and kangaroo tripe roast is no longer appealing? Don't they worry about slipping on the pools of blood as they do the conga portion of The Fabulous Periwinkles dance?
So my question. What do you do in your fort to keep it clean? Particularly the outside portions that don't get rained on. My solution is to build floors over the surface, leave them there until sufficiently bloodied, and then remove them and rebuild them. I do the same with the walls, doors, windows, fortifications (have to get that crossbow bolt out), everything. Honestly, this is rather time consuming and it always seems that after doing so another buzzard flock decides to descend. Any other solutions? I do like a little blood and vomit and broken crossbow bolts, but not so much that I think my dwarves are living in an Evil Dead movie. Thanks!
