Hi kdriver58,
It turns out that this particular address is pretty confusing to work with. There are several options that come up in search results:

1. 635 Old Hickory Blvd, Nashville TN - That's on the north side of I-40 at Exit 199.
2. 635 Old Hickory Blvd, Old Hickory TN - That's an industrial area, Wise Manufacturing is the business there.
3. 635 W Old Hickory Blvd, Madison TN - This address is recognized by Google Maps, but not by USPS. I don't believe that this is a valid address.
4. 635 W Old Hickory Blvd, Madison TN - This is a house on the corner of W Marthona Rd.

I'm assuming that you want the first one, but I'm not sure. The problem lies in the fact that Madison TN and Old Hickory TN are both incorporated parts of Nashville, so Nashville could be reasonably inserted as the city name in any of those addresses.

If you would, please let me know which of those destinations you are looking for. I've made a few changes already to them to help differentiate them, but those changes will take a few days to process. In the meantime, I'd like to make sure I know where you are trying to go so that I can give you the most accurate information.

Thanks!
