Very nice, beautiful indeed.
Just curious, was the red rock expensive in NJ?
It can be scooped off the ground east of the Cascades around here, and the extinct volcano in the city here is littered with it... did you have to ship it in?
I ask because I'm not aware of many locations in the US where the red lava rock is abundant. Not every volcano produces it (Crater Lake/Mt. Mazuma for example, grey pumice. 3 Sisters however, red rock. The explosion type depicts the result). It's cheap and commonly used around here, but not so pleasant to walk on barefoot (although one can get used to it). Fabulous for weeds... if they seed, they they pull right easily :~}
