Nice, a cool ride report RIGHT AT THE beginning! Subscribed, this ought to be good. Looks like "for the earth" is in for a good one.
Really cool that your dad was not only able to join you, but that he posts up here as well! I have had my twins riding with the wife and I since they were 5, they are 9 now. Hard to find proper road gear for little people, end up purchasing it from London England every year or so as they grow so fast, but TOTALLY worth it as we are building memories.
Once they are grown, I plan on riding WITH them just like your dad does with you.
Ride safe man, looking forward to your RR as it unfolds.
