As I said before: y'all know the drill!
It's riddling time!
For those of you who don't know, every so often I do a special for a mile stone for this book.
This one is for 10k, as stated above.
Alrighty, here's the riddle:

I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I?

Now, remember! I'm putting my trust in you guys to not cheat and search up the answer! It has to be your genuine guess!
Good luck guys!!
