Camping and camping gear. It can be so cheap and easy, but when you start buying high end gear it adds up quick.

Not to mention the different types of camping, backpacking, car camping, glamping, etc. Car camping “overlanding” gear is awesome, but so expensive.

Is that really true haha

Edit: seems like it, so cool!

Does IR sensor count? I loved that on older phones so much.
