I'm going on a road trip from Dallas to Vegas and I'm planning to take pictures all the way. I have the T2i and want to make sure I have all the things I need to take great shots! I plan to go to the Grand Canyon, Hoover Dam, Carlsbad Caverns, Petrified Forest, the mountains and of course the lights and sights of Vegas. What size and class of SD card do you recommend? What ens do you recommend? Can you give any hints? I'm not an amateur photographer, but I'm not a pro yet either. Thanks to all in advance. I'm leaving in mid October.
