Move to Maine
A friend of a friend of mine was apparently bitten by a Brown Recluse spider on a visit to Maine about 7 or 8 years ago (Islesboro, in Penobscot Bay). He was bitten on the thumb while picking wildflowers. It became infected and the doctors had to amputate the top joint.
I think these things are fairly rare, but it's always possible that one of them may get into that proverbial shipment of bananas or otherwise hitch a ride into new territory.
