If not, consider organizing one yourself. Ask area businesses to sponsor the event, offering free food and games in return for the work. Local kids will have a day of fun, businesses will gain publicity, the park will be a nicer place, and you ll spread a wonderful message. On rainy or cold days, the opportunities for low-cost outings seem few. You ll need to be more creative.
Libraries are a great place to spend some time, often hosting events such as movies or story hours.
Instead of going to the local library branch, consider making a longer trip to a bigger library in a large city. Often taking up several floors, your family may be amazed at the materials that can be found there, sometimes including museum quality exhibits. Instead of just choosing some books and leaving, stick around for a while. Your family may be able to listen to music and other recorded material, browse stacks of magazines, or look up old newspapers on microfilm. For a few cents you can make a copy of the newspaper from the day you were born.
