Out-of-State Yellow Letters - local P.O. Box vs out of state address?

[Jim Tiernan]

What do you think works better as a return address when mailing yellow letters out of state?

A local p.o. box in the area where the letters are being sent?

Or the address where I actually live in another state?

Not sure how many people would be turned off by each. And trying to figure out if it's worth the expense of a local P.O. Box

Thanks,

Jim
