When was the last time that you spent one-on-one time with your son?
When was the last time that you built something together? 
Made something together?
Hiked together?
Cracked jokes together?
Told stories around the campfire?

What will he remember?
Will he remember the time you camped out at Emerald Bay, where you hiked, canoed, made smores around the campfire, TP'd the girl's tent, sang songs, skipped stones, and generally goofed around?

Will he remember when you took the train down to San Diego, slept overnight in the Shark Tank at Sea World, and then had breakfast with Shamu in the morning?

Yes he will.  Yes you will.
