I haven't had a chance to review much of season 2 yet so I apologize if these topics were covered, If so I'll have to watch the replay of it when it airs or pick up the dvd.
I'd like to see some more tactics involved when traveling. For instance you obviously can't have a pistol with you on an airplane. There are also times you may be traveling from state and state and enter one that is very non gun-friendly (Illinois), or could have someone that does not poses a CCW license so they carry their pistol in their car a different way with ammo separated and unloaded, locked up, etc. Some tips and tricks for those kind of situation would be great. Most international travel is going to involve not having a gun available, so topics on that would good as well.
Maybe some specific situational issues involving being in the south west and running into drug runners/cartel types. Also dealing with gangs and such while traveling through cities. Possibly expanding the idea from defending yourself from single or few attackers in many different situations to group mindsets should a worst case scenario happen and you find yourself in a bad areas of the country/world.
I know TBD survival covered this idea slightly, but say for example you get off the highway of a major city in the U.S. and find your self downtown in a gang territory where your threat awareness goes through the roof. Topics like that I think would work very well, both for teaching how to blend better and not draw attention but also defending yourself should a group attack occur.
