Hi Jim,

I do a lot of landscape photography and have to lug around a heavy Manfroto tripod (not complaining about the weight because it sure sturdy). However, you may be able to get away with using a bean-bag of somesort. Something you can rest on a wall or rock (the beans will help mold around the shape and give you more support.

Also, I agree with Paul. you are also better off with a cable release. Mind you, if your camera does not support this, you could always use the self-timer option. This is always a great little backup.
