I completed the 10,000 plts challenge (I'm up to over 20,000 pts per run, and for someone who can't land a Tony Hawk trick that's pretty good!).

I need to knock 4 ladders. What ladders?! Everything knocks ME down! Is that a literal knocking down some ladders (where are they?) or BMX lingo speak? Where are the riders I'm supposed to talk to?

Thanks!

Yes, these are actual ladders you have to knock over. There are four hidden throughout the stage. It took me a little while to find all four. But just be patient and you will. When you get near them they will glow a neon green (like all the other challenges you need to accomplish later on). Just grind, wallride, or run into them and that's it! Good luck!

To get you started there is one running from the pool to the building. Just run into it and it falls.
