Hi Brend,
Thanks for the info. I will be more than happy to send you a shattercone
also, no problem.
I'm an amateur astronomer here in Montana and have just recently been bitten
by the meteorite hunters bug, and realy enjoy the hunt.
I enjoy this list, everyone is very helpful. Thanks List for all your info.
