You mean Simpson? As far as I know they don't hand out keys, but many employees have keys. If a gate is locked there should be no one driving. If the land is not posted, it is USUALLY open to hunting. It may be closed right now due to fire danger.
I suggest contacting the land owner about access related questions.
WELL I KNOW THERE IS A SIMPSON . BUT THERE IS A SMALL LOGGING COMPANY THAT OWNS LAND AROUND HAGG LAKE AND GRANDE RHONDE. IS THAT SIMPSON OR STIMPSON? I WOULD LIKE TO KNOW BEFORE I GO LOOKING FOR A CONTACT NUMBER.
When placing a trail camera don't just look for a well used trail. What you want to do is look for a freshly used trail off by itself that goes from a north facing ridge, thick forest, brushy knob or some other similar bedding area to a food source. Don't forget water sources. Especially in the summer months the deer need water so look for a good trail going down too a creek surrounded by thick cover and place the camera 100 yards up from the water source.
Scent control is very important...
