At summat past 70, I happily haul a chain saw, fuel and oil, wedges, hatchet, a McLeod, and various other implements of destruction on a Bob trailer without noticeably blowing out my knees.Because I'm not gonna dork up my sweet steed putting a rack for a MFing CHAINSAW on it? Duh.
It's hard enough pedalling with a hoe, plenty of water, a big hat and a folding saw. Taking a chainsaw in would save hours but I just can't be stuffed.
Also, technically you're still pedalling that thing - it just lets you carry a lot more stuff without blowing your knees on the first hill.
Suck it up, princess!
