I can help with everything before crumbly woods in RCT1 except for evergreen gardens and dinky park. My question is: How can I pass crumbly woods? There's too many trees, and there is barely any room for anything! Help?

Dinky park is a snap if you bridge the highway. You can buy permissions to build over the road in two places that i have found. One the front of the park entrance and one near the back of the park. You can build over the road and then expand your park on the other side.
