Hot and Cold

This evening I took a quick walk into town to try and search out a blip . It was rather grey and overcast so struggling to search out a decent blip shot. I blipped this crane the other week but this evening I took another shot and decided it looked quite effective in heat map mode. I really like how the buildings show up as rather cold. 
Back home relaxing after a busy day  at work , it will be the same again tomorrow due to staff been on holiday or sick .
