We are leaving in the morning and will be in the parks Tuesday afternoon through Saturday. The forecast says high in mid-70's? I have decided on short sleeved shirts with jackets, but should we pack shorts, pants, or cropped pants? Also sandals or socks and sneakers????? I just keep waffling and don't know what to do. We're from the Texas panhandle and it is going to be in the upper 90's here today. In fact, it's already 86.
