How do you get rid or trees?

Select the scenery toolbar and right click on the tree in question.

Double right click with mouse

1. Go to build ride.
2. Then select any ride.
3. Now right click on the trees you wanna get rid of. But each tree you delete will cost you $15 so watch your money.

Click on any of the build menus and right click the tree, right clicking anything while in build mode will get rid of it. Except in one park, one of the last three or four parks doesn't allow you to move the land at all, or delete trees, (they do leave spots that you can go underground with) this park is a really big meanie... You have lots of trees to go around. :D It's hard to make coasters, but generally make it only in that map... It's kinda like Dinky Park, those two parks definitely get there own specially made coasters, If I had my Saved Coasters from when I had beaten the game on my Desktop still it make it easier.. I had some real loo loos.. :D

I want to add white lines so I can have roads how do it. And want more to add to my game. Such as scenery add pictures for billboards. I want to add things in general to my game like anything I can download to my pc game. I feel I do not have much to use in rollercoaster tycoon 3 and want to add more to it.
