Query: Cal Poly Alums Must Have This Book!

Through this great read, Maxwell Long did an excellent job of documenting and illustrating the diverse history of Cal Poly. The impressive photos and unique perspective allows the reader to get a feel for my favorite Central Coast town and University! I highly recommend this book to anyone interested in San Luis Obispo and require that loyal Alums buy it today.
