That's the spirit of the season. Good for you.
Sounds like you are into it.
I mentioned to my Girlfriend that I might do that (the wreath thing) to my Jeep last year. She didn't get excited about the idea. Don't know why, one has to have a little fun.
Bought some Christmas ball type hats at the $ store for $1.50 each (Santa, I've been GOOD or Seasons Greetings or Merry Christmas on them). Gave 11 of the 20 I bought to employees at a local McDonalds where I often have breakfast and read their free newspaper. Gave them a little Christmas cheer on a Monday morning and some fun for me as well. Will also give those hats to a local parts supplier that I purchase from, The Parts Guys at the local Chrysler Dealership, a local repair shop, the person that cuts my hair, my grandkids (along with Advent calendars as of yesterday) and some others. I ran out, looks like another 20 more will do it.
So YES .... Happy Holidays (once they arrive), Seasons Greetings, Merry Christmas, Happy 2011 and all that. May your days be merry and bright. Keep the spirit.
