St. Patrick's Cathedral on New York's 5th Avenue is a must-see, when you're there. It's the largest decorated gothic style Catholic cathedral in North America.
We went to see it years ago and lit a candle. The experience was really spiritual somehow.
I remember us sitting on those very steps in front, because we were so tired from all the walking around the city. It was worth it though. Had so much fun.
A big 'thank you' goes out to Squirrelsohno for sending me this beautiful card for the North America April Round Robin.
