No need to pretend you like rock stacking if you don't. Personally I cannot understand it being a greater nuisance than litter, and it doesn't damage the environment, either. (Of course, I would not remove rocks from stream beds where I might upset the eggs of fish or amphibians...that would be damaging!) But, there was plenty of rock stacking to be seen before I started adding my contributions in this area. (one of the reasons I feel so at home there, I imagine)
Yes, I understand why you brought it up. If it is a nuisance to you and not enjoyable, then it is the thing to mention.
Happy soakin'...wherever you do it!
