Ok, I'm sure this has been asked before but I did a couple of quick searches and didn't find it. I am awaiting for my LTCF application to get processed and mine has already expired. This Saturday I'm planning to go to the range with father in law. He has his LTCF. I know that legally I can only transport my pistols directly to and from the range. I'd like to go run a couple of errands after the range.

As long as my FIL is with me, does his LTCF cover transport of all firearms in the car if we run some errands, or can I still only go straight to and from the range?
