I thought I was the only DR1er to ever visit the flea market.
Not that I am cheap or anything, but I love nothing more than a flea market or thrift shop. I have some pictures of that same flea market somewhere, but I can't be bothered to find it.
I have bought a lot of old books from that flea market, other than that I can't recall ever finding anything of value. I would love a good thrift store here.
The one in Ciudad Colonial has mostly antiques and assorted trinkets. I am not a collector so I never bought anything either.
