Hi Doug, Steve & all....Doug I think you may have really hit on
something- Refrigerator Meteor-Magnets! Every refrigerator should have
a couple....You can etch them and use them to hold up your shopping
list, chore list, etc. I think we'll start offering them on ebay in the
near future! Even better...Tom might be able to etch a picture of Granny
on the meteorite and we could have etched-granny-meteorite-magnets for
everyone's refrigerator!


Cheers & thanks for a great idea!


-John
