During a recent library acquisition in Boro Park, Brooklyn, my bookhunting took an adventurous turn. After being led in to a house by the owner of the property and the books, I was left alone to box and cart out the books. Not 2 minutes later, Shomrim pulled up and demanded I explain what I was doing in someone else's house. Apparently, a neighbor saw someone they didn't recognize moving boxes out of the house and gave Shomrim a call, and do their job they did. They asked me for ID, called the owner of the house, confirmed all was ok and only then, leave me back to my task.
But I got my first New Order, by Arthur Szyk there!
