Leaving for OTS in few weeks - Questions

Can any current OT or grads shed some light on the paper clip track? Is it a mile loop then a half mile loop? Or six laps like a traditional track for the PT test?

Also for OTs flying in and staying on base, what's the process for transportation in the morning from the inn to the dorms for in processing? Is it just the on-base taxi phone number?

I was expecting it to be pretty hot still from September to November. Advice on if I should pack for lower temps? I am trying to pack as light as possible and eliminate items that would just sit in the dorm and not be used.

Any packing advice would be great. I have been using the OTS packing list website and OTS welcome guide and double checking posts here.
