LEGZ30
LE
I think this is the first picture I've seen of her where she looks genuinely happy rather than a forced smile for the cameras:
I've seen that facial expression before, it's the look of a teenager thinking "Bloody hell, this is a bit scary and I'm cold but I'm actually doing something I never thought I could". I genuinely hope she gets something out of this trip rather than it being just another photo opportunity.
It would be pretty funny if she arrived in the US and said she was bored with the environmental stuff now and wants to take up yacht racing full time.
