Cachebusters Challenge

OK, so not long ago this challenge was brought to my attention: I Challenge You To Play ... CACHEBUSTERS! Well OK, I accept your challenge. I tend not to give too much thought to challenges in parts of the country where I am not likely to be caching, but you never know when you'll be near enough to pick it up, and of course, you normally have to actually do the challenge first. Plus, realistically this one is en route to Swansea so maybe I can make a detour when I next go.

Right, so this challenge is a little different from all the others I've seen because it's less empirical.

You have to complete a line from left to right in this Blockbusters-style grid:

So where to start - let's forget the path across for a moment and see which ones I do already somehow qualify for:

Stung by Nettles. OH YES. But how do I prove that? Just got to find a log where I've complained about it, I guess.

Go Caching at Night. Easy one - use the night cache, Dark Side.

Find a Cache Over 2000ft Above Sea Level. Not sure about this. My highest in altitude is First in Wales. Don't know the height of it though, which is a bummer.

Find a Cache Underground. Uh, don't think I've done that one. Found one in a cave before, but it wasn't underground. Will have to look into this.

Have an Encounter with the Long Arm of the Law. Amazingly enough, despite being pretty inconspicuous sometimes, and caching in foreign urban environments, no one in authority has challenged what I'm doing, and certainly no law enforcers.

Get Stuck in Mud. I've got pretty damn muddy at times, but never stuck.

Climb for a Cache. Yeah, can think of a couple of examples, and a photo of myself on a ladder.

Find a Trad, Multi and Mystery in 24 Hours. Done and dusted on more than one occasion. Most memorable being 6 types in one day at Big Pit.

Abseil to a Cache. Oh, I would if I had the equipment!

Go without Caching for more than 30 Days. You frickin' kidding me?! I'm not that crazy!

DNF the same Cache more than 3 Times. I certainly have done, but I don't know that I've ever logged my DNFs more than once. I am normally content to DNF for the first attempt and then keep schtum until I find it.

Chased by Cows. I had a pretty horrific experience with a cow whilst caching once, but I don't know whether chased is the right word when I was the other side of the fence.

Walk more than 5 Miles to find only One Cache. Oh, probably, can't think of an example though, or how I would prove it.

Swim to a Cache. I doubt I will do this, but never say never.

Go Caching in at Least 3 Different Countries. Check.

Forget to Bring a Pen to Sign the Log. Oh, yes, definitely. Perhaps a "here's a photo instead" log will suffice as proof?

Forget Your Coat and Get Caught in the Rain. Undoubtedly. Can't prove it though.

Get More than 10 FTFs. Done, and have the stats to prove it.

Go to Hospital with a Caching-Related Injury. Now this is something that will happen in time. Just so long as I don't die or permanently damage something (like my spine!) I would probably revel in this one.

Move on at Least 20 TBs. Easy!

Well I have done plenty of them, the only problem is I can't possibly complete this challenge until I have done one in column 4: i.e. I have found an underground cache (only know one and it's nowhere near - please post suggestions below); have abseiled to a cache (do you have the equipment? Let's do it!); have swum to a cache (I will if I have to, but I can't swim very well, so I'd rather not); or have been to hospital with a caching injury. This, as I've said above, will probably happen at some point but I am not going to tempt fate! Will be amusing telling the A&E staff that I "just had to get that little plastic box" though!
