Yesterday my light stand came crashing in the wind. A mild wind. I do have a decent light stand but as the light was high up at slow winds it was swaying. I did use a sand bag
Physics wins everytime! Use more than one sandbag.
...but was wondering when you move to a remote loc how can you do it without carrying the weight of a sand bag
Either use a cart or have someone help carry them of you.

Free your eyes and the rest will follow. (With apologies to George Clinton.)
A couple sand bags are heavy? Head for the gym and work out. You'll become a better photog too.
You could also carry empty sandbags and fill them on site if material is there to fill them. Then empty them on the way out.
I carried some 30 pounds of camera gear through the Himalayas. Felt like 200 pounds after 70 miles... but I was in shape. Makes all the difference.
