Okay, I checked out the well-written Challenge Guide. Lots of good info there for the bridge and tower activities.
Depends on who else will be there, but I was there last time when you were leading the activities. So if you’re not there, I’ll have some idea of what to do.
I live near Monongahela, so it would be some back-and-forth for me to pick up the playbrick from Josh’s on Saturday afternoon. It would make more sense for somebody else who lives closer to pick it up and take it back, but I can if needed.
