Hi Mitch! Excellent photo for the last banner image of this year!
Not sure this is common in other countries but, in Portugal, at midnight, many households give a noisy 'concert' by banging pots and pans that are not in good condition. By doing so, they say goodbye to the Old year and welcome the New one.
At midnight Lisbon skies blaze from several points in the city. I took this photo last year from my apartment..
In Lisbon, the main new year's eve party is free. The party consists of concerts by popular musicians and singers. It's sponsored by a Portuguese beer company. Yesterday, I saw this man giving away top hats for tomorrow's party...
Best wishes for a Very Happy 2018!
