Golden Ears Way:
199A/201St -> one or the other per this rule. Maybe 199ASt as it's the exiting one; what would be signed if they didn't sign control cities instead?
I'd go with 199ASt, based on its being the lower number.
I was getting ready to pull in that change, and run Datacheck on it, from my old laptop. Then the laptop failed, perhaps permanently.
If it doesn't come back to life overnight (as has happened before), I'll e-mail the revised file to Jim tomorrow for him to plug in. Once I'm back from a short trip to North Carolina, I'll resume work on completing the transition to my new laptop, including figuring out how to submit Datacheck-able pull requests from there.
