I just checked time and temp, it's 4 am and 70F in St. Louis. I'm planning to take off for a week or 2. I'm thinking I should take some light fleece jacket and my tights if it gets below that. I'm thinking prepare for 20* below what normal/average temp is. The extra clothes are almost a kilo, that I might not use. Is it good insurance or not??
Anything else you bring that you hope to not use?
