Today I found a cache with 8 trackables, yes, eight. 6 were travel bugs, and 2 were geocoins. I took 3 travel bugs and 1 geocoin since I know they're safe in my hands and that I will log them, and pass them on. From the ones I didn't pick, two had pretty specific goals that I couldn't help out, and I left the other two for others to find.
There's alot of travel bugs that were listed for the cache but weren't there when I showed up. It seems like alot of trackables go missing, or randomly appear (without being logged) from the cache that I found them in. I feel like I probably should have picked up the other two with non-specific goals because of the caches tendency to lose or gain trackables mysteriously.
