Cache may found .... search thorough place.
I am in this superb a location here.
I struggled with this puzzle though. I spent a lot of time researching Firefly, to make a good puzzle about a series that was tragically cut short.

I learned a lot about Mark Sheppard, who is arguably the biggest sci-fi actor out there. If you aren't sure, consider checking his wikipedia page.

But when considering Crowley (ie: Mark Sheppard), one cannot trivialize the contribution of Hugo Weaving (ie: Elrond). So I spent some time cruising his wikipedia page as well.

Once you've delved this far into puzzle research, you may as well keep going, so I followed up with Joss Whedon, who naturally led to Nathan Fillion, who naturally led to Neil Patrick Harris.
This train of thought only has one natural outcome though.
DR. HORRIBLE'S SING-ALONG BLOG!
Roughly 47 minutes after starting with the Sing-Along Blog (which has some profanity and adult humour in it, so please be cautious when sharing with little ones), I was back at the task of creating this puzzle.
Another week with no ideas, so I went on a road trip. Here are some of the things we saw on the road trip.
Excellent viewpoints across British Columbia and Alberta.
Colorful arrangements of flowers along the highway curb.
Exquisite lakes, rivers, and mountains from Yoho, through to the Saskatchewan Crossing pub.
Absolutely beautiful glaciers along the scenic parkway.
Breathtaking vistas everywhere we drove.
Cars lined up along the roadways, parked in droves for camping along Abraham Lake.
Daring passing of cars on long-weekend road.
What three words summarize the challenge of building this cache?
1) exhaust
2) conflagrate
3) asparagus
So, I eventually realized there was only way to culminate all this information into a single puzzle, and I sat down and wrote this one. Now that you have the final coordinates, please go sign the cache log.
