We finally completed our first "real" interview for the blog and wanted to share it since Andrew Hatchett Michael Daniels Heather Kraafter and Sheila Hensley were so helpful in getting us comfortable with HOA.  We've got some fun plans for this new video series and hopefully we can get to the point where we have a whole community of kids participating and asking questions.  Thanks again for all your help!
