Thinking of going to AMS in late September, anyone been there during that time.If so what is the weather like.Is it cold already or just kinda cool. I generally travel light (carry on) and will dress accordingly. Thanks

I'd say... "kinda cool." . At least an all purpose sweater and an anorak style jacket with a removable liner would probably keep you traveling light, and comfortable. Gloves don't take up much room either. Warm hands are a bonus when touching the sensitive body parts of a short time friend.

Enjoy, Oldster
