I was at a function the other evening and met up with someone I hadn't seen for a while. She told me that she might be moving north and would be looking for a house for a short period. I told her about my house sitting adventures, and she was quite impressed. She'd thought of house sitting with her husband, but didn't know how to go about it.
I gave her my card - and she said she'd contact me for information, which of course I'll happily supply.
I haven't heard yet.
