I think a lot of you guys who are suggesting workarounds are missing the OP's point. I know it's been a long thread so people can't have read all of it, but he is spoiling for this fight. He has a political advocacy group providing his legal counsel. He doesn't want to "get away with it" on a technicality, he wants to get the restriction thrown out.
That's admirable that he's putting himself out there and has chosen the more difficult path of taking on the whole law because that's the one of ways laws like this get changed. But that also means he can't expect to have the judge award him a victory on a technicality like the other side's counsel didn't show up, if the resulting judgement could potentially change laws and have a widespread effect.
I bet if he was just some guy who wanted to camp on his land and not a plaintiff working with an advocacy group trying to invalidate the law, the judge would have been more willing to give him a default judgement for the missed notice and the other side not showing up, to allow him to go back to camp quietly on his land. But that's not what he wants. He wants to force a change in the law.
Given that, working around the law by technically not camping while really camping is also not the victory he is looking for.
