With all the "really keen" gear in the backpacking world and all the interesting trips folks take it seems to me a backpacking/outings show would be a natural for a once a week TV series.
It could run on the same days and back to back with one of the survival shows.
I mean c'mon, it could be a classic Sierra Nevada route one week, a Florida Everglades sea kayak trip show another, a winter backcountry trip another, sea kayaking New Zealand, a "light and fast" (but camping) JMT trip, a Minnesota canoe trip or a Canadian dogsled trip, pack rafting some remote south western river, etc, etc. And then there are all the cool trade shows. Just as interesting as a car show - for us, at least.
And hey, with the dimunitive size of decent digital movie cameras why couldn't there be a once monthly amatuer show of a trip that somebody took of their AT hike, for ex.? Two or three of those could fill an hour.
Then we could have a 5 minute segment on the latest gear or some poor gearhead in a 12 step program to wean him/her away from shopping. The opportuiities are endless.
If hunting channels can show kids hunting or women's hunting or the latest huntin' gear why can't there be enough of a market population for OUR outdoor hobbies?
