Ripp, 9-3x57
I agree. Sticks are definitely useful, but I'm not a fan and prefer to use terrain, trees, or suitable shooting body position. Even Boddington has written numerous times about missed shots and shot opportunities due to PH insistence on shooting off sticks. I dislike being told what to do, but relish well meaning advice... I don't carry sticks, but use them (or not) if they are available.
Regarding the original post - I reckon Peter's solution may be the best, unless you have a truck and can carry a heavy wooden standing rest such as those gunmakers use for regulating DRs...

Ripp - good hunting on your trip!
