What a duo.

We pulled in for the ubiquitous Brew at Hilton Pk Services.
As we stopped, a bright white Harley pulled in beside us.
Funny, I thought, pulling a Bike into the caravan area: anyway, useful, I can pick his brain.
While commencing to pick said brain in pulls ginormous Mobile Home.
It transpired that they liked touring, he/they was/were Biker(s) AND no way was he going to loiter within Tent. This combo was their solution.
However, brain picking yielded lack of knowledge.
Seemingly, Stateside, a Bikers "Hat" laid on the ground to rear of bike is akin to a cry for assistance. The bloke who's brain I picked was unaware of this gem so couldn't verify.
