I'm on a mac, all my applications have the font "intrepid" I've been using for everything... now i need to find this font suitcase but IT"S NOT THERE!!!

This has been pissing me off to no end!!!!!

the finder application can't find anything named "intrepid" anywhere on the harddrive. yet it's listed in all my programs. Does anyone know where it might be?
or does anyone have this font that they could send to me? please?

it's a sans-serif font, it looks very similar to "futura"
