Sitting here with a sappy grin reading this. My dad did something similar over 60 years ago and I remember the fun like it was yesterday.  You are doing a good thing!  My grandkids are at the other end of earth and it makes me sad that I will not get to do some of these things. 
Only thing he insisted on was wearing a helmet and that stuck with me through the years before helmets were required.
