I once took a piece of wood through the rear spokes (fortunately not the front!), and it came up and around and tangled with the mudguard struts. Unless the wood would have fall out of the wheel before reaching the seat stays, I cannot really blame the fender. Fortunately, I was able to keep the bike upright through the abrupt rear wheel skid, but it got pretty exciting.
