December is just one of those unpredictable months. When we went last year, we spent a day at the pool. When we went the year before that, we wore light jackets a few days in the park and definitely in the evenings. The first year we went, we packed both jeans and shorts. I've found that so far, the temps haven't gotten so cold in Dec that I can't wear shorts all the time, so I don't pack jeans anymore. However, I do find that I wear a light jacket and/or sweatshirt quite a bit...especially at night. For some reason my legs don't mind being chilly (so I can wear shorts), but the rest of me needs something to keep warm!:shrug:
