Thanks you all for your support and appreciation.
All the glass was in the serenity pool. It looked as if the bottles of Bud where on the dam wall of the Womb, and where acidentally nocked down in the the Serenity pool with the obvious consecuences.
I did no cleaning in the Womb. It was pretty clean as it was. I only vacumed the Serenity pool which as many of you know takes quite a bit of time due to the only slight difference of water level between this pool and the creek.
The sand bag used to cover the drain of the Womb had been thrown in the Serenity pool on top of the glass.
I did not hand the brochure to the college kids because it is not approved by the Forrest Service. I did warn them that both camping and fires are illegal and could result in fines. They asked the amount and I told them between $50 to $200. It sounded tht the amount was a fairly good deterent for them. Hope it works.
