Darrin,
We have caught more visitors than I can count climbing up onto the bridge the dangerous way (using the fence around the deck and holes in the superstructure as footholds). You'd think that they were at a rock climbing facility.
The scopes are wrecked (they need to be overhauled by the original equipment manufacturer, like Cavalla had done a few years ago).
Rick keeps the bridge hatch chained and locked from the inside. So, there's no way for them to get in at that location.
The few artifacts left on the forward bridge, like the TBT, are practically scrap metal due to lack of maintenance.
