<p>Thanks for the advice Eric. I bought a spare battery just for this trip. The D7000 battery is no slouch and I have never run mine dry in a day of shooting but I didn't feel comfortable with no insurance in the event of some strange, catastrophic event.<br>
About the macro shooting... I don't know if there are likely to be flora at the canyon where the 60mm would be desirable. That's what prompted the post in the first place. I know it will be spectacular and awe inspiring but I know nothing of what desert flowers may be cropping up along the way. Since most posters think it will have little value there, I have already shed it and one of the flashes from my bag as well as the MB-D11 grip.<br>
As far as memory goes, I have 6 X 16gb Sandisk Extreme SD cards (@ 45mb/s write speed)and can bring along another 2 Lexar 400X 32gb cards. The Lexar's are slower to write but other than bracketed photos, I don't anticipate running seconds of shots off for anything. They would be my backups.<br>
I have never had much luck with monopods for stability. I've owned one for many years but never learned to trust it much and with my hope to take bracketed shots for HDR's, any movement would mess with my chances.</p>
