Oh crap, I forgot to update this...
I actually finished most of it on Saturday!!! We weren't able to finish because the farmer was expecting us to be finished the following week, so he didn't bring the materials. My dad and I are going out this Saturday though.
Also, I did a fence refurbishment instead (Same museum though), the process that it took to get there was ridiculous though. First it was 'build 25 brand new sections of fencing', then they figured I should just repair the one they already have, so now it was - replace a few posts/rails, then it changed again less than 2 weeks before we started to 'Okay, just remove 20 years worth of debris (It actually only took a day to clear, but it was a lot), put in a new post, re-nail the cross bars, and tighten the wire fencing'.
But, it's almost complete, and my leaders say it's still valid.
