One thing that a ton of track builders forget to do is to remember to consider driver stand pov. Because you need to be able to see the car pretty much all the time you should pick a good drivers box position and continuously check the vantage point as you build. No sense having an awesome obstacle if you can't see the darn thing lol. The best thing you can do for yourself is to make your driver box have elevation. If you have access to an old shipping container that seems to be the best as you can stand on top for the drivers box and store all you track maintenance gear inside to keep things simple and on hand. Also keep your slowest car that you will want to use on the track as well as the fastest car that you will be using so that you can check your jump gaps. I use the slowest truck to check my double jumps and my fastest to check my triples. Having a track that feels really fluid and that cars of different power can enjoy is the trick to keeping people coming back and to keep you interested as the owner. Just out of curiosity were in the country are you building this (weather is important) and what type of dirt do you have at your disposal? There is a ton more to consider but these were the ones i wish i knew before i got into it. Be prepared for some trial and error, hope you have a small kubota at least to save your back lol Good luck with your endeavor and don't forget to post some pics! oh and another thing i forgot to mention is to remember to think about drainage. I saw that you said that you had standing water which means that the ground doesn't drain very well so you may wanna get some cheap piping to allow so water run off. Standing water can really damage some tracks, nothing is worse than seeing all your hard work get literally washed away!!
