Oops

So we have a mail service company in South Dakota.  They receive our mail and sent us an email telling us who the mail is from.  We then email back and have the service destroy or forward it to us.  We just need to tell them where to mail it.  We have it sent to a campground we will be staying in the next week or so after we get the info they have mail.  So while 90% of our communication is electronic, we do get some snail mail.  So, we changed the addresses on the accounts and such that were needed.  Then we learned that one of us (likely Bob) had the wrong address...by one number in the unit number.  So back we go to change it all again.  Frustrating.
