Thanks everybody! Great comments and info.
I wasn't really referring to preventing burglary, but loved Ron'Da's comment about the "big, mean dog!" Yeah, that's probably the ultimate answer to uninvited guests........
And TA, as far as someone using my post here as an indicator that we're "rich" and going to be away from home......... Wouldn't that be ironic since we are FIRE and have mentioned that, but there is literally nothing of value in our home? Our home is modest and in a blue collar, middle class neighborhood and we don't own any art, fancy electronics, etc. Someone would really be surprised! Of course, that's how we got to FIRE!
It turns out our solution is right here all along. Normally while we're away, out long time nextdoor neighbors and good friends take in our mail and keep it at their house pending our return. Our trips are usually in warm weather, so there's little to go wrong inside the house. This time, we've asked if they wouldn't be so kind as to bring our mail into our house daily and check the temp, etc., and they've agreed. Walking their dog and watching their house so many times over the years while they're away is paying off!
Again, thanks for the comments and discussion!
