I regularly do a lot of front country outings: base camp or stay in a cabin and then hiking, fly fishing, etc. One of my neighbors, now that his kids are all in college, wants to do a couple of short backpacking trips this year in the Boundary Waters, UP or the Northwoods in the Lake Superior area. I am already over-thinking my camera kit. I will probably take the O-MD, O12, O12-50 & O40-150. I am thinking of taking some Milky Way pictures and I will probably take along my underused Gorillapod. We will be light but not ultra-light. Eight miles a day on average. Any thoughts or recommendations?
