First of all, I was just at the slab last weekend (2/16). All was good then, but that was before the rain started. The river in Llano is up a little but not sure how much, couple of inches I think. Might still be OK for run on 2/22.
Next question, I've been all over the river around Llano, the area in town is not quite like it is at the slab. At the slab if you upstream you'll find some rocks available for crawling. In town and west of town there aren't as many rocks, it's mostly sand. But I can show you every entry point that can made leagally.
