Ok given the no landing operations don't seem to work a different scenario:
There are forrests of gigantig trees and your crops or lifestock live in the crowns of the trees. Your standard operation is, that you blimp over the forrest, lasso strong enough branches (insert some biobabble why strong branches stick out far enough to be lassoable) and then enter the tree crown.
You can't get there with ground vehicles, you definitly can't use planes. Optionally you can add a technobabble reason why grav vehicles disrupt the ecosystem, or have a local superstion that says so.
Does that work? Johannes _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
