I have to admit to a certain feeling of superiority as I watched those who weren't in bathing suits rolling up pant legs to try and get a little wet without soaking their pants. Every time I saw someone re-roll his pants, I just waded out a little farther. The cool ocean air felt wonderful and we had a great time.

wife(Elva) and I also go to the LEFT coast quite often to walk and wade in the surf. I in my kilt(are)(is)(am) ready to enjoy the water, but Elva always wears long pants and as you said needs to rollup and be careful not to get them to wet. This Also gives me a good feeling.
