transportation

I live in FL, and I want to purchase a rifle from a shop down the street from my place. I don't have a vehicle to transport it home in. Can I just carry it directly home on foot, and if so, what legal and safety measures should I take?

Can anyone confirm that I will not be committing a felony if I transport a handgun from my LGS to my residence while riding a motorcycle? I plan on having the gun locked in the factory-provided case, which I plan to carry in my backpack. I'm new to the forum--I'll introduce myself properly...
