Testers needed

Hi I'm working on new B&M Stand-Up and a need a few testers before I start working on the scenery. In addition to testing there is also one favor that I need to ask of any testers. I'm having a hard time trying to create a path for the entrance and exit. So maybe if you could, create a general path for me by drawing a line by using a small steel beam for the exit and a large steel beam for the entrance. You could also remove trees if it helps but moving of supports is not allowed. It would help a lot.
