Something I was slow to catch on to when shooting pictures at vintage bike shows was to take one shot of the show placard with the bike so that I could know for sure later what make, model, year, and maybe who the owner is. I'm certain I looked at the placard with this bike; I should have photographed it too because trusting my memory is getting increasingly risky.
Digital "film" is cheap, unlike 36 shot emulsion film rolls in the old days where every shot cost real money for film, processing, and printing and none of those things were reusable. So your tip of the week is to shoot more pictures of each bike including the details like the show placard. There are more than 36 exposures in most camera memory cards. Take more pictures of your friends too, they are at least as important as the machinery.
