Nice...I always try to walk whenever possible. From the skyway connecting C & G, can I walk into the car rental area? Looks like you show the entrance at 2:25. Do you know if it is open for exit from security to car rental? Traveling MN in two days.
I think that was an old security checkpoint that is now closed (probably since MSP is under renovations) so probably not. Best bet is to find the central “airport mall” and follow the signs to baggage claim from there.
