Since he posted the comment on your Montana Mountain Loop
video, he must mean Hewitt Station Road has a 'new' gate. It has been closed for some time due to the dust raised by all the ATV/4x4 traffic.
FYI, there is a large sign at the 'ATV Staging' parking lot across from Picketpost which has a map showing the bypass route, which is FR 252.
Other than that, there is no way FR 172 or FR 650 will be gated due to private property
issues... until Resolution Copper begins dumping their mine tailings,that is.
