The humidity is unusually high today- around 88% The local park was very vibrant and active, with a young soccer team and a group of people throwing frisbees. On my way back home I noticed several policemen checking parked cars along Green Valley Circle. One group had what looked like a kit with a brush- I wondered if this was for fingerprints. Had the humidity of the air affected which fingerprints could be lifted off car doors, handles and windows?
