The tires on my car are filled with Nitrogen. Lately, I've noticed one of my front tires has low tire pressure. Is it ok for me to fill it up with regular air? Do I have to go to a place that has Nitrogen?

Fill it with air - you won't notice the difference, and I doubt it will make any noticeable difference to the life of your tire.

Air is already around 78% nitrogen, so getting pure nitrogen would probalby not result in any benefit such as better gas miliage, slower leaks, or increased safety. The low tire pressure is probably from normal leakage and colder temperatures in Fall. Maintaining proper tire pressure with regular air will be much more beneficial.

Riddance is right. There's no problem with filling up with regular air, but the advantage to Nitrogen is it's not as susceptable to pressure changes with temperature.
You can find Nitrogen at welding supply shops.

The reason for nitrogen filled tires is the air inside does not expand or contract with heat/cold as much as normal air. It's supposed to help with tire longevity, and so you don't need to check your pressure as often.
You can use normal air without it hurting your tires. Most tire shops have nitrogen available for free as well.

Theres no point in filling up tires with nitrogen vs air, unless youre racing (even then it doesnt really matter). Air is ~70% nitrogen anyways, so you wont be hurting anything.

I don't know where these geniuses get their physics, but nitrogen expands and contracts about 95% as much as air. The only reason to use it is in racing or space shuttles or somewhere you worry about exploding tires feeding oxygen to a fire.
