Hey, a little secret... Don't know if you've noticed. Now it's getting sunnier, blacktop gets REALLY warm. Fun to feel, but damn it DO get hot. WOOF! Now it does leave a pleasant gray on the soles, but they can also be left sizzlin'. Just a warning.
If it's a parking lot, you can do the "white stripe shuffle," where you walk on the white stripes...scamper across the blacktop to the next white stripe, etc.
