Tony's been building radio towers around Temba. These do one thing right now, and that's send a signal to the Whale Comb Sent Her that will ring some bells, alerting anyone there that there is...someone at that particular radio tower. These are designed to work when the network and power grid are out. I'll put them on the map eventually, but right now the location and amount of them are yet ambiguous, so I'm open to where you want one of these to appear!
Since they've gone up, he'll also have been putting some work into building little saferooms in the building that a tower is on, so that might be something for you to...mess around with.
I am not precious about them. If for whatever reason, your character's reaction to them is to tamper with/change/destroy them in any way, feel free.

Tony's also enlisted Cal's help in making a little fleet of vehicles for the Barrys. There might be a bunch of tiny cars flying around.
