Science is kewl.
I was reading up on Star Trek (yes, I'm a trekkie. big surprise) and I remembered reading about Bussard Collectors in Niven's Known Space series. Who wants to strap millions of tons of rocket fuel on your back if you don't have to. That shit stinks and it's been know to blow up. I like my appendages where they are, thank you very much.
Just hook these babies up to your ride and you can mooch your fuel from the black. No fuss no muss.
Then you just need to wait the 5 or so years it'll take to get to Alpha Centauri at light speed. You'll probably need to bring a book or something.
