If you live in Portland Oregon - check it out: the Chinese Garden is offering FREE complimentary admission until Jan 11th. They are celebrating the 10th Anniversary with 10 days of free admission and there's a schedule of fun free events as well.
So why not go down and take your camera and check it out. This would be your one and only opportunity to sit in the tea house and have wonderful little snacks while watching the rain drip off the fancy roof tiles and sip Tao of Tea teas from special cups - all without paying for admission to the garden! (you still have to pay for the tea, but usually you'd have to pay to get in the garden as well) And its such a perfect time of year to go. Seriously.
Rain + Chinese Garden = Wonderful.
