It's actually funny. I didn't know about the shorts rule in the paddock either. When we saw Lloyd on Wood day (which was f'n cold also) I got into the Paddock with shorts on. I noticed people giving me looks (but I just though it's because I'm extremely handsome
), but didn't give it a second thought. Until after the race when one of the security guards told me about the rule. Thankfully we were on the way out anyway.
