there are other options for the strengthening exercises. i went shopping and *may* have spent too much money. based on state police reports, the trip was not school-related, though there were a number of 6th and 8th graders aboard, as well as a number of high school-age kids. there are four seasons in a year, i like summer most, while i don't like winter, because in that season, there are so many rainy days. please note that product availability will differ from country to country.
