I retreated to Key West, Florida for the past week so I could relate to Garrett's temperatures. Chicago was brutally cold, but now it is mid 30s. Had a great time as always down in the Conch Republic. Went over to Fort Taylor and saw what they used for rebar in the Span Am War fort retrofit. Nearest one is a 300pdr Parrott. Figure there could be 50-100 or these barrels entombed in the walls...
