I'm working on it during my spare time after I finish homework each day... It's slow but I will finish

^Yeah i had some difficulty keeping mine under the length limit but I managed to do it (Rough track) with 500 ft too spare.

Question 1: By bunny hills do you mean airtime hills/camel backs?
Question 2: At what point (degree of banking) does an overbank become an inversion?

I'll give it a shot and try my best considering school is starting up again this week. Still stuck on NL1 so it's nice to have a contest that I can participate in.

Question: What are the rules regarding support scenery (ie. Station, transfer track)?
