i am interested in some volunteer work. i am a stay-at-home mother with a three year old son. i can get a babysitter for a few hours per week, but when children may benefit from your exhibitions i would jump at the opportunity for my child's exposure to this genre. our family moved here two years ago, and i would like to become more involved in the community that i have grown to love. let me know if there is anything i can do to help. my background is in geosystems and ecology, but i am always thirsty for a new advent.
