Tried out the bike sharing thing. Lessons learned: power assisted biking is definitely fun up hills. Second point learned: everyone using bike shares are really, really tall men, because all the seats were too tall for me even on tippy toes (and I couldn't seem to adjust them) , and I'm 6 ft tall on my tippytoes. I had to lean back on the skills 9 year old me acquired at jumping off bicycles.
