Ranger freefalle7 is right on target when he wrote
Bring whats on the packing list and you will be ok.
In 1981 I rode a motorcycle from Iowa to attend Ranger school visiting family along the way. About 500 miles into the trip I dumped my duffle to repack/adjust the load on my bike. I discovered my little sister had given me a going away present. In the bottom of my duffle bag was one of her training bras.
I don't even want to think what the RIs would have said/done upon seeing it when they had us dump our gear on day one. I figured I just missed becoming a legendary Ranger school story. My sister still thinks it funny.
Just bring whats on the packing list.
