defending my PhD thesis in late June, I took one month off for this road
trip as my relax/recharge vacation before starting my postdoc
position at UPenn. In the past Shu-Wen and I always went backpacking as our
special way to celebrate graduations. This time we decided to do this in
an American style to celebrate probably our last degrees in our life time.
Though road trip doesn't seem to exactly match our travel style, we thought
after 5-year stay in US we should at least experience some spirit of it.
By combining the road trip with favorite visits to national parks, this
trip actually turned out to be a sweat, wonderful and unforgettable
memory of our lives.
