I loved my days as a kid skating down the hill road just outside our house, you didn't have to put much effect in as the steep incline did all the work, just enjoy the wind whooshing through your hair (it was the 1960s and we all had long hair back then) climbing back up the hill again however would've been a lot easier if I'd had these balloons.
