Went out on Liberty Creek trail on Monday. Glassed for two days before the opener and saw nothing. I started 30 miles back and worked my way back to the crowds....no caribou. I didn't see a caribou, alive or dead, for three days. Stopped by chaos ridge (chicken) and more of the same reports. I had a friend go up towards Eagle and he saw nothing. I don't know where the herd was but it wasn't in Zone 3.
