Can you take a toy bow to the airport?

I need answers quick because I leave tommorow morning. I have a toy bow that i wanted to take back to America but I'm scared I ll have to throw it away. I don't have space in my carry on so I wanted to take it in my hands. It's fairly big and has pink ruffles and a string from made from cotton. I won't be taking any arrows or sticks with me and I could just put it in the overhead cabin but i don't know.

How can I pick up a GPS signal from a passenger seat in a commercial airline?

I'd like to pick up a GPS signal while I'm a passenger in a commercial airplane so that I can know where I'm and how fast/high I'm flying. Also, I think it would be pretty interesting to watch the approach to/departure from airports on a map as they occur.

So far I've tried holding up cell phones by the window (with airplane mode on and Wi-Fi and phone off) but haven't been able to pick up a signal.

Has anyone else figured out how to do this? Maybe with a device other than a cell phone?

GA Airport Security?

Most GA Airports do not have a police department so who takes over security? Is it Airport Operations? If so, would it be wise to equipt them with bullet proof vests, pepper gel, and pepper ball guns? Or is that illegal? Obviously they'd have proper training for any equipment.
