Ok, I have looked at the weather averages, and it looks like the days will be plenty warm enough, without being too hot. However, I have heard that it can get chilly in the evenings. So does that mean the mornings will be chilly as well, and we will need to dress warmer at opening to the parks? And when people say 'chilly' does that mean we will need long pants and light jackets, or are shorts ok with a light jacket or sweatshirt on the arms? Do people find it too hot to wear pants/jeans during the days in Oct? Is rain usually a problem the first week of October?
