If I were you, I'd use your new wheels to make a run to a coffee shop or a grocery store. Running errands by bike is a good way to learn to negotiate traffic without overwhelming yourself! I love to spend a Saturday morning tooling about, doing some errands and getting in some miles!
It's a great looking bike! Congratulations!

"I rejoice every time I see a woman ride by on a bike. It gives her a feeling of self-reliance and independence the moment she takes her seat; and away she goes, the picture of untrammelled womanhood."
Susan B. Anthony, 1896
