Marina, I didn't realize that you have been around long enough to have "known" these people! You look so young for your age.
I live in an area of hills and valleys that were carved out by glaciers all those years ago. There is an incredibly colored rock, very soft, and a rose colored brownish red, that is plentiful here. When the sun hits it, it is almost a neon color. It often makes me stop and catch my breath for the sheer beauty of it. When spring comes around again, (we are already frozen here with ice and snow), I will try drawing with it. I'll have to do a search now and try to identify it--------my geology is a little rusty!
I guess you could call this "getting back to nature".
