Oh yes! Ghost towning too! I have a serious fascination with most things old and decaying...particularly buildings!
Where I live you're likely to come across all sorts of things just by going for a hike in the woods. Usually the only thing left standing from an old homestead is the brick or stone chimney, but once in a while you can still see more.
Do you have any bottle houses over there (houses built primarily/entirely out of empty soda or beer bottles)? We have a few over here, and they're some of my favorites!
Can't say I have heard of those, they would quickly collapse due to our terrible weather.
I dunno about that, they're pretty sturdily built! Some are even pretty. Check out this one (not my photo, hence the link):
Hmm, that didn't work very well. Let's try a simple copy-paste. https://www.americansouthwest.net/california/calico/bottle-house_l.html
