A couple of traditions around here in New England are
Take the dc for a walk or a drive at dusk in the runup to Christmas to see everyones outdoor/house decorations, some neighborhoods plan together and hand out sweets to the dc coming to look. Its very festive and builds community, some of the more able adults help the older ones etc etc.
Cookie swaps, no one really does mince pies or Christmas pud, but most people have some cookie recipes they bake every year that they give to friends, serve at gatherings, give to teachers etc. So you dont have to bake a whole lots of different ones, people get together and bring a couple of dozen of their cookies and then everyone takes home a few of all the other peoples, while having a fun party at the same time.
I do miss the town street decorations strung across the roads though. I havent seen them around us. Most towns put swags on the lamp posts and wreaths on shop windows, and then one main tree for the town (or more if its a city).
I decorate with a tree, stockings, a mantel covered in pinecones and candles, some festive bunting /swags things and poinsettias. The dc have taken to winding tinsel around the banisters and made paperchains and 3d snowflakes out of paper and all my sellotape! We then wind fairy lights around a couple of the pine trees on our drive and if I am feeling flush with time I might try and put some lights on the porch. My favorite decoration though is putting candles in each window facing the street. They are battery operated and turn on at dusk and off 6 hrs later and make the place look some welcoming and cozy (I actually leave them up until the snow melts in March ish)
