For me, I've learned that a lot has to do with the type of cache that I might be FTF on. If it's just another roadside micro (picked up about 8 in one day fairly close to home - no big challenge), then I'm in no rush. If, on the other hand, I know there's a new cache out there, hidden by someone I recognize as placing good, and challenging hides, then I'll go for it. I definitely don't cache at night, we live in a very rural area, narrow roads, few lights, sometimes questionable terrain, etc. I'm always happy just to see another new cache in our area!
