Hi Anita, I use guest speakers and field trips with my students as well. I like to have recent graduates come in because the students see them as peers and can relate to what they are saying. It is funny because the guest speakers say the same things I say but the students listen to them better because they are out in the field working at what they are training to enter. They don't stop to realize that I made my living for many years doing the same thing and chose to move into to education and say my knowledge with them. Kinds like listening to your parents when you are a teenage. What could they possibility know? This is what makes teaching so much fun. Gary
