We checked into our hotel and headed to the catacombs. 2 trains and about 10 stops to get there. There was a long line 3/4 of the way around the block. It was raining so we got in our place at the back of the line and Pedro went to get umbrellas. The security guy said it was going to be 3 hours. We took turns running errands. First to get coffees and then to get macaroons. We entertained ourselves with "eye spy" and watching the wildlife. Pigeons, sparrows and some really cute rats.
