The SAXOPHONE page
The saxophone is a much larger band instruments. The case will not fit in your backback but it's easy to setup. Saxophones also require a good amount of air and finger dexterity (ability to move your fingers) to play. The sax is pretty easy to start on however if your hands are not large enough to reach around the side keys then you may have difficulty at the beginning. Consider how well you are at memorizing fingering and how well you are able to control your fingers if you choose to play this instrument.
