Cricket,
In Colorado, you may enter your child in extracurricular activities even though he or she is homeschooled. They can be in band and other activities with their peers.
I am aware of that. We did that with dd13 when she was younger and we were homeschooling. The reasons we aren't homeschooling with dd11 right now have more to do with finances (my p/t job pays about 1/3 of our bills and has our family health insurance) and dd and I having some difficulty working together. Right now, dd11's school set up is working pretty well for her. It isn't perfect, but not bad.
It occurs to me that you are maybe referring to dd13. She really isn't a kid who does a lot of the school extracurriculars aside from drama in years past and honor society. Her extracurricular interests tend to be outside of the school realm: she's open water scuba certified, does some rock climbing, volunteers at an animal shelter, etc.
