RE: buck rubs...
i didnt notice any....but try not to touch anything with my hands while im out there...especially right now....i know i did more than enough damage just being there....but i never like to physically touch rubs or anything....just me.
but i looked for it and didnt spot any...ive never found velvet...i bet you gotta be there QUICK to find that stuff...between critters and bugs and it drying and shriveling up, its probably not EASY to come by...
