Articles like this one make a trip to the Tetons worthwhile and I wish I had of had this information when I went a couple of years ago. Well, that and some good weather.
Why?
Because it makes spending the entire day there worthwhile. Get up, do a shoot along the river, hike up to Solitude Lake and back, followed by collapsing in bed, only to wake up early the next day and repeat but with different destinations.
Earlier in the year I came across some pictures for Mt Assiniboine trail. Jaw dropping stuff *and* you won't see what's there to be seen if you won't walk more than 50 yards from the car. Something else that I wish I'd known was there before.
On the easier side, I was at Glacier National Park last August. Whilst the drive up the "Going To The Sun Road" is very pretty, when you get out of the car and start walking a mile or two or for the entire day, the landscape explodes with possibilities that you just don't get from the car.
Now maybe if you're taking photography tutorials, you do a morning thing and then spend all day doing class/critique/technique - but not when you're on a "photography" holiday.
I think this website would be doing itself a huge disservice if it didn't cover more material such has been presented with this topic. Whilst there's been articles on packing cameras for flights, which cases and weights, there's been nothing that explores what it means to hike for 12 hours at 8000' up (last year I did a couple of walks at Mineral King - Sequoia National Park) that started at around 8000' and climbed up to over 11,000' and back in a day. Regardless of how good any manufactures primes are or how sharp a L zoom is, do you want to carry extra pounds of glass and metal or food and water?
