Hi Bethany,
You can connect with nature no matter where you live in the world. To celebrate Beltane you can do a simple outdoor ceremony, grab a candle, some fresh flowers, a cup with water or wine and sit in the woods for an afternoon and have a picnic inviting the fairy folk, saying some prayers for blessings. Your parents don't have to be present. The fairies especially like the innocence of youth and to celebrate so just remember that being a witch is simply making a connection to Nature.
namaste,
JB
Take what you wish from my words, and blow the rest away.
