This cache is at the historic Ogden Union Station. You are looking for a set of three plaques. Please take time to read all three plaques; they're short. The first part is at the bottom of the top plaque, and the second part is the number at the top of the middle plaque.
You will need to email me both numbers to be able to log this find. Do not post any of these numbers in your logs, even encrypted.
You don't need to wait for me to reply before logging your find. If there's a problem, I'll email you. If there's no problem, I may email you back.
While you are at the cache location, you can visit the many attractions or even catch lunch.
15 May 2015 update to logging requirements: I have informally also allowed a photo of visitors at the Union Station. Now I'm making it an official option. You have the option of posting a photo of you at the Union Station at a distinctive outside landmark at this Union Station. So, you have to at least have the front (east side) of the building with doors, windows, the fountain, a painted horse (at the station) or the water tower will do.
