Where are you going?

Yesterday my wife and I took a road trip to see a waterfall and find a Geo-cache (one of her hobbies).  The trip should have taken 45 minutes or so of scenic driving along the Allegheny river.  As we neared the destination we came upon a large bridge spanning the river.  There was only one problem, the bridge was closed for repair.  If you've ever driven around western Pennsylvania you know the problem we faced.  The only way across was to go back the way we came, work our way back away from the river until we can to a parallel route and then proceed.  In the end, the trip to the waterfall took an hour and a half instead of 45 minutes because of that one obstacle.
Is there a lesson here?  If you know where you're going, and are determined to get there, obstacles cannot keep you from finding your goal.  That's not bad, how about this as well, that which is worth doing is worth doing even if it costs you more than you'd hoped.  It was certainly a lesson in patience as well.
As we finally neared our destination, the TomTom told us to proceed down a dirt road that led to the falls.  After about 100 feet, the "road" took an exceedingly steep nose dive and we clearly no road, but rather a four-wheeler track at best.  At that point I put the car in reverse and backed on out of there.  We ended up getting good directions to an easier approach to the falls from the guy whose property bordered our would be "road" and made it there just fine.

Is there a lesson here?  Just because you think you know the way, it doesn't mean that you should throw yourself off of a cliff to get there.  I've heard of people whose GPS devices lead them into Death Valley where they become stranded (and their lives in danger from the heat) because they don't stop and think whether or not the advice they're getting is wise.  Thankfully, I decided before it was too late that reverse was the wise choice.
I thought we were just going for a ride, little did I know there were life lessons on the way there.  By the way, the waterfall was beautiful and I helped Nicole find the Geo-cache too.
