hi John (I assume this is fremiet) - my biggest piece of advice would be - Dont forget your tripod - I left mine in the hotel room at the North rim of the Grand Canyon and had to shoot all handheld - its possible if your brace yourself well but not ideal :). Try to get there for a noon tour - thats when you will find the best beams as the sun is overhead the narrow slot canyon. Consider a photographers tour - these are more one on one and the guide will stop the regular tourists while you take your shot - might be worth the extra cost. You have to use one of the guide services - we usedhttp://www.antelopecanyon.com/upper_antelope.html. I am sure you will have a grand time - it is a fabulous place! ~ gaurav
