I have a friend that is a famous professional meteorite hunter. He says that there were a few that might have caused some fires, but it is a very rare situation with freakish coincidences.
Thanks for the post Islander7. I live in the U.P. and found the articles interesting. While bird hunting two years ago I found what appears to be a small meteor impact sight (fresh). I hope to locate the spot in the spring and now have a good GPS to mark such stuff. Have another spot to investigate near my deer blind.
