The Park was Closed-Conspiracy?

We were very disappointed yesterday when we arrived at the park to find it closed for the day. The park official claimed the playground area was being treated to get rid of some sort of grass that has burrs in it. However, Sean isn't exactly a "stick to the sidewalks and trails" sort of kid and we have never seen any of this dangerous grass.

Jonathan was immediately suspicious. He thinks there is some sort of government testing going on up there. When I pressed him for details, he clammed up. Now I am suspicious of him. Sean took the news of the park closure surprisingly well. We expected tears when we had to turn around and leave, but he was calm and collected like he knew the park was going to be closed. Jonathan and I are both suspicious of Sean.

And to add fuel to our conspiracy theories, Mr. Goose has been walking with a limp the last few days. We asked him what happened, but he is being evasive and ducking the question. Jonathan theorized he got caught up in some of that dangerous grass, but I am suspicious.
