I also recommend getting some decent tent stakes. I use these: https://www.amazon.com/dp/B075QK5XNC
The stakes that come with most tents will work. However if you are on any sort of rocky terrain forget about it. The Gorge is fairly soft dirt which is a different problem. The cheap stakes tend to pull out during high winds. If you plan on keeping your tent for future festivals. I would be sure to stake and guy out your tent securely.
Something like this will do the job for a tent, canvas, or shiftpod. I've used them on all three for years. Mallet/hammer to put in, twist out with your multitool pliers:
