I'm flying into Yellowstone and trying to pack and wanted advice. I have 4 bodies. I was thinking about bringing 2 bodies. I have a 1DX. Obviously, my favorite to use. I have 1d mark IV, 7d and 5d mark iii. I have cf and sd cards, but my sd cards also work in my camcorders and they are larger than my cf cards. I was hoping to bring my Motorola Xoom tablet to save space. I was thinking about taking the 7d and 5d3 to save space (charger is much smaller too). I want to take pics of birds in flight and astrophotography. I am bringing my Canon 600 f4 and my 14mm f2.8 Tamron. My 70-200, both 1.4 and 2x extenders. I also will bring my 35 f1.4 and 24-70 f2.8. I am leaving behind my 85 1.2, 100 macro, 400 f2.8, macro extenders and my 17-40 f4.

Am I making any mistakes?
