Was out in zone 28, public land. Had two spikes come in and munch on acorns from 8:35am to 9:15am. Also heard some guy using what sounded like a Primos Buck Roar for all it was worth. He blew it loud, long bursts, every 10 seconds or so for about 90 seconds...every 20 minutes, like clockwork. The spikes just looked over that way (about 100 yards away) and kept on eating acorns.
The smaller spike had velevet covered 2-3 inch spikes, the other one had longer spikes, with the velvet dangling off the bases. At about 9:15am, the "grunter" got down and sent the two little bucks scampering away. He did some scouting my way, saw me, waved and went on his way, so I bailed at 9:30am.
A little video of one of them.
