Yes we did, and we didn't find anything like that. We also looked for sign of deer antlers in the bows but didn't find any. We see deer rubs alot but these didn't have any of the sign. We also searched the area for tracks and found partials but no definate track. The ground is full of leaf litter and it makes it hard to find complete prints. Sorry about the shot angles but I did my best

Depends on the surroundings. Some I think are dominance related ( like beating on the chest) some are used for marking areas.
