I am always in a quandary about how much to say when I see something abjectly dangerous. For myself I have decided to go ahead and offer up a concern and leave it at that. Not to be critical just cautionary.
However renegade and disparate, we are a community so let's ante up and help the ignorant climbers bent on killing themselves and others.
I'll send 'em my one inch military spec webbing. IIRC, I still have probably sixty to eighty feet of it, and I haven't used it in years. Seems like they could use it far better than I can.
With that, a few biners, and some knowledge, you can set up a toprope just about anywhere.
Send me a PM, and I'll send you the gear.
Sorry, can't help out on the knowledge part - not on the East Coast anymore. But seriously - telling these folks to hire a guide? 90% of the posters here could show these folks a couple of safe ways to set up an anchor in about an hour. None of you can take an hour out of your weekend to just show this lady a thing or two before she's involved in a serious accident?
