I made a few small grammar and formatting changes and added a featured image. This is a terrific post, and I’m very glad to see that you enjoyed Flock so much. 
I did make one change of significance: I changed a reference to “6 days” toward the end to be “four days” to match the title. If you want me to revert that, I can. I assume you’re including the travel in it, but it was a little confusing to me as I read it.
