Jump Zone angst

I just passed the 75K mark in my latest wip, Jump Zone. A very small part of me is pleased because I've never written anything this long before. *yay*
But I'm groaning because I should be typing 'the end', except it's no where in sight :( therefore, I am a terrible judge of plot and/or pacing, take your pick. And I may eventually have to chop very large chunks of it out because if I continue to ramble along at my current pace, I've easily got another 10-15 K before finishing.
And people... it's just not THAT kind of book. It's not supposed to be all introspective and deep. It's supposed to be a futuristic adventure with bit of fun and action.

But... I don't feel like I should hurry it along at this point or it will seem just that... hurried along. Don't you hate books like that? Where you sense that the author just wanted it DONE ALREADY?
*looks to heaven* Please don't let that be me. sigh.
