You have two whole horses? Congratulations.
Did you train those horses yourself or did you buy them trained?
And if your 4H is anything like the 4H around my area ...... being in 4H is nothing to boast bout (sadly).
Regardless, just from your couple of posts on this forum, I highly doubt that you are ready to handle a mustang.
1) You think it is an emergency to get a round pen, when you haven't even sent in your application yet, when even if you did, you don't get the horse until March.
2) This sounds like something you decided 15 minutes ago. Have you seriously thought this through and/or gotten the approval of your parents and/or have a trainer to work with?
3) I lived in Oregon for 3 years, just outside of Portland. There's plenty of farm stores to go and BUY some panels and make your own round pen. If you don't have the money to do that, then maybe you shouldn't get another horse. (Who potentially will send you to the hospital = $$$$ in hospital bills)
3) And if you don't know you can buy panels at a farm store (since you said you need to know where to find these), then again, maybe you shouldn't be buying a mustang if you don't even know where to find basic supplies. Expect to spend almost $1,000 on a round pen. Panels are not cheap. Plus you'll need hay to feed this horse. Some sort of water source or tub. Once the horse is even touchable, it'll need vet work, farrier work, dental work, etc. All those things another horse costs.
Unless you have more experienced training background to give us, you ARE a teenager and we have no reason to believe (at this point) that you are capable of adopting and successfully training a mustang without you getting seriously hurt, or without the mustang getting seriously hurt.
We are not judging. We are concerned for your safety. If you are going to post on a public forum, we aren't just going to pat your back and tell you "good job". We are going to speak the truth. You've got to grow some skin (and maturity) to handle the truth.

It is not enough to know how to ride; one must know how to fall.
