Coming up with ideas for things to do throughout the summer isn’t always easy. But the Arlington County Department of Sports and Recreation has hundreds of classes available, and registration opens tomorrow, May 23.

Examples of active kids’ classes are swimming and tennis, creative classes include music and theater, and crafty classes include woodworking and ceramics. A wide range of activities is also available to adults, including knitting, various sports and gardening.

The catalog of courses is available online, as is a request form to have a copy sent through the mail. Registration can be done online starting at 8:00 a.m.

Although registration forms can also be mailed and faxed starting tomorrow at 8:00 a.m., and phoned or carried in starting on May 30, online registration is recommended to expedite the process.

Registration for those who are not residents of Arlington begins on June 6.
