Where were you? Often times I see open gates during archery and muzzloader season but they are rarely open to vehicle access. People still drive in though, past me on my bike. Constantly. It's got to be posted with a green dot or with the bright green signs on green diamond land saying its open for recreational access.
Us archery hunters get kinda screwed on access but it's better that way to me, the animals are much more easier to find and hunt without guys driving around in their rigs.
