Bonding in Texas

So here we are in Texas hanging out with my in laws for Justin's spring break. It's been such a great week so far. The best part of my week has been that Justin and I have been bonding like crazy! He keeps wanting to cuddle with me, play nerf guns, wrestle and read books. I'm loving every minute of it. I just adore this little guy so so much!!!
Justin is a boys boy. He loves his dad and loves to play with him so I usually back off and let the two of them play. I've noticed this week that he has been craving that kind of attention from me. I think he's starting to realize he can do those types of activities with me so he's been all over it. It's been fun but exhausting too. Haha! Call me old! Yesterday we ran around for over an hour having a nerf gun fight! He would have kept going but my old lady knees couldn't take it anymore. :)
Okay, so here is where I need your help! Do any of you have any fun activities you play with your kids that your kids love? There is only so much sword fighting, nerf gun fights, etc... you can play with a kid. I was just thinking maybe I would ask around for some tips. Are there any creative activities you do as a family? I would just love to be able to give this kid more variety in his days and give us some fun things to do together. Any ideas would be greatly appreciated. And as they say in Texas 'Thanks Y'all!' ;)
