Always good to get up and about and enjoy the serenity before the crowds, the viaduct is amazing what a feat of engineering, the sculptures are damn cool as well.
Hope your cold is short lived, tbh I haven't had one in years, but always found that getting out into the cold air and inhaling deeply through my mouth helped, no medical science behind it other than the voices in my head suggesting that bugs prefer a warm cosy place to live and a prolonged blast of coldness would disrupt them. It usually worked LOl, but there again, I have alien blood.
have a good week ahead
