 ## Arriving early
 
-If you want to arrive earlier than the [tbd] you are expected to help with buildup. Bear in mind that there won't be much infrastructure and most likely you won't be able to setup your tent in your desired location. 
+If you want to arrive earlier than August, 15 you are expected to help with buildup. Bear in mind that buildup is hard manual work and there won't be much infrastructure and most likely you won't be able to setup your tent in your desired location. 
 
 To keep track of the number of people on place please register with the orga or the angelsystem if you want to help during buildup. 
 
-**DO NOT ARRIVE BEFORE THE [tbd] ANNOUNCED DATE**
+**DO NOT ARRIVE BEFORE THE ANNOUNCED DATES**
 
 We simply do not have the infrastructure to support many people early on. There won't be enought toilets, no showers, no power, no water and no food or anything else needed to stay. We need space to operate heavy machinery and those do not mix well with squishy humans. You will be asked to leave.

+### Kids
+
+Especially if you are bringing kids with you we ask you to not arrive early. The camp will be a construction site with heavy machinery driving around and unsafe places everywhere. Do us and you a favor and not bring kids to buildup. If you do it against all advices, we expect you to watch for your kids. If our machinery has to stop because of your kid, we might have to ask you to leave the site. Please look after your children, camp buildup is no outdoor playground.
