Well, they just keep coming. Andy sent in a tip about No. 48, connecting a thread from North Oakland to Schenley Park. I found No. 274 on Fifth Avenue and, based on The Master List, suspect it helps connect the North Side and South Side protractors. My friend Allison found No. 291 and No. 295 — among others — on the Eliza Furnace and Riverfront Trails, respectively. Rich sent a photograph of No. 301, the new high number.
