Founder of IHP, husband to a great wife (my best friend), and dad to 5 wonderful kids. Big fan of history, quizzes, and just about anything trivia related. I also enjoy reading biographies, non-fiction, and fiction (fantasy novels). My other hobby is board games and in my opinion there is nothing better than a family board game night!
