Well it is not necessary to erect a May pole lol Honestly it depends on you and what you think appropriate and what you are willing to do. You can decorate your home with greenery collected outside as this represents the Goddess. The May pole was actually used as a phallic symbol for the God. Have yourself a little feast preferably with red fruits, salads and oatmeal dishes. You are going to have to wait quite awhile for the next Beltane celebration so you have alot of time to plan.
