Vaughn, just do it! maybe in the summer but hey you have some time to get fit
Perhaps in 6 years when my boys graduate from High School! Plenty of time to get into shape, and I'll only be 61! But I might leave the 8x10 behind and get a nice light 5x7. That might fit on the bike without needing a trailer! Something tells me my wife would not be a willing participant.
At least with LF landscape, a bad day of photography can be a good day of exercise.
