I try to keep it close, so it is at least within reach.
Usually it's in the truck, acclimated to the cold, and ready to go. Take it with me when I hunt and bike. Problem is the weight of the 7D and L lenses forces me to restrict myself to one lens, or lighten up on the hunting gear, and, pray I don't crash on the bicycle. Usually I have the 300mm attached, and out of the backpack, in case I run into a quick shot opportunity. And carry the lighter 100mm in my pack, in the 300mm case, for selfy shots and macro's. I can't cover the distance, to get into the frame in 10 seconds, with anything longer than 100mm. 24-70 is too heavy, unless I leave the 300 behind. So landscapes are usually out while hunting. My light weight rebel is only 6.8mp, or I would take it.
Now that hunting is over, and it's been around zero degree's out, the camera is back inside with me. I'm not going anywhere,either.
