Yes - Marfa can present challenges. We need a new meter so when I call up AEP - they tell me that the street number already had a EID# and a meter - even though it doesn't. We do not have postal delivery in Marfa so house numbers were made up for years - just pick one. So many homes may have two different numbers - one that relates to old utilities and new numbers for 911 emergencies.
So my meter adventure requires that I convince the 911 representative that the current numbering on the block is wrong so that a spot can be opened up for the new meter. Any way one looks at it, people will now have to change their street addresses - crazy!
