Oort Clouds a Problem?

Would oort clouds of debris (should they actually exist as hypothesized) cause a problem to leaving a solar system? It seems to me they would. You don't want to be traveling toward jump speed and then be ripped apart by random debris. I think they would have to navigate through and beyond the massive debris field before approaching jump speed, and of course, this would require quite a bit of travel. Of course, solar systems are so close near the center of a galaxy that the debris fields would probably be closer together than they are to their own stars.<br /><br />But then Voyager (V-ger) travelled half way to the next solor system before it stopped transmitting so it obveiously didn't run into any trouble.<br /><br />Thoughts?
