thank you all for your helpful comments! i really appreciate it.
betty - thanks for the book recommendation. i was looking for something new
to read. i just finished "emphasis art" by wachowiak & clements (very good -
i'd love to find something of similar caliber for high school)
robert - i live in maryland. ideally, i'd like to get certified through a
program which would be acceptable to other states if i were to move later on
down the road....but maybe that just complicates things....
