More: Rex is the greatest pup, my best friend and adventure pal. He does everything with me: Mountain biking, hiking, skiing, fishing, trail running....The list goes on. During Covid I have been teaching from home, and Rex has become a source of motivation for my 5th grade students on Zoom. When they need a little break from Zoom class they ask for Rex. He has become our mascot and a huge reason why my students show up. When we go back to in person learning, the kids want Rex to come to school too.
