@stackhodler My $10k, two-month backpacking trip through SE Asia with my new girlfriend (now wife) still remains, to this day, one of the best times of my life. Currently planning the next SE Asia trip with our two young kids.
@stackhodler This hit even harder when you count how many summer you get with your kids. You only get 12 summers that really count.
Age 6-18: Old enough to do everything and young enough to want to do it all with you (at first). Then friends, independence and opinions are competing.
