Children Camping during the school year teaches your children that education is not just for school - they can learn new things everywhere. Taking time off from school teaches your children that their relationship with you is very important - even worth missing school and work for. Children will be able to learn more in the camp grounds outside of the summer months when there are fewer children in the parks. When you are home schooling your children your classroom is wherever you want it to be. Many camping areas are simply not accessible in the summer time.
Some parks are full all summer.
Many parks are not pleasant in the summer. Parks in the southern U.S. are terribly humid all summer long and desert camping in the southwestern U.S. is dangerously hot in the summer.
