Have you looked at Amazon:

I agree that a GPX download should be an option for those who want it.

I was looking at the 'logs' for the new Labs in Painswick, and people are reporting poor phone signal there

I guess that's why most Labs are tours of larger towns and cities, rather than more rural areas.

Still don't like how they are treated differently to other caches and now no GPX file either

HQ have said that they’ll be on the main geocaching map by the end of this year. They also said that it’ll be easier to find caches and complete ALs at the same time - so I assume that the Lab app will show caches, and vice versa (maybe tapping on a cache in the lab app will switch you to the geocaching app).

But I agree - even if they do that, there’s still a long way to go. Why can’t their name be listed on the GC website leaderboard (it just says “Adventure Lab cache” for each stage)? Why can’t they show up in your list of finds (clicking on the name could just send you to the app download page)? Why can’t their size be listed as ‘virtual’, or simply ‘other’? Why can’t the CO give a D/T rating for each stage?

I personally don’t mind the requirement to use the app... it’s just one of many cache types.

One thing that also annoys me, which isn’t HQ’s fault, is that Project-GC doesn’t count labs (unless you pay). I understood this when they were exclusive to big events, but there are thousands of permanent Adventure Lab stages across the world now. So, surely they should treat them as a normal cache type?

Thanks Walk Tall - need to do some more caching, but not know if its worth the effort as they seem to pop up as log the caches we have found!

How many do you have to get for Wonders of the World?

There are severn in each: Modern Wonders and Ancient Wonders but you have to complete Modern Wonders first, before you can collect the Ancient Wonders.
