After the Allreds left, I got the itch to pack one of our bags with some souvenirs and clothes that I will not need for the rest of the mission. We are allowed 2 bags each weighing not more than 23 kilos which comes out about 50 pounds. After stuffing this bag with lots of stuff, it still came up about 7 pounds light so I am pretty sure we can make it home without paying extra. I did find out that we can up grade a bag from 50 to 70 pounds by paying a flat rate of $50 which is cheaper than sending it home almost any other way.
