Going to Mendoza!

I just bought bus tickets to Mendoza for next weekend. It's a province to the west of Buenos Aires where there are actually trees.... I am quite excited to go visit my friend Alex. He plans to take me on a tour of the local wineries whereby I will be drunk by the end of it as they offer a glass of free wine on each tour. I must remember to pack some food as to not have an empty stomach. I also imagine that I will be given a tour of the local pub scene. Which will be a quite nice change of scenery. Excited as heck to get there but I will be on the bus for about 16 hours, during the day. I can't get an overnight bus, as I have to work late the night before and miss all the buses out of Buenos Aires. Still, excited to go!!!
