I do cycle to forage - there's a patch of wild garlic on my commute!
Well you have plenty of opportunity to notice it on a bike. Wrong time of year, but the commute takes in plenty of blackberries, elderberries, wild hops, some sloes, and....roadkill. There's generally a dead pheasant on the road every couple of months. I've never collected them, but I've been close. You know they're fresh if you do the route twice aday, tho I guess someone who know's their stuff would be able to tell. A fresh badger appeared this week!
The blackberries, the couple of times I bothered to stop last September, I was picking a 1-2 kg per hour. Hardly made a dent in what was out there. Inexustable suppy, at least for my uses.
I dunno if you could eat well from foraging, but it can't be any worse than a couple people I've seen on tour - just chomping bowls of cheap museli to keep going and no eating out or cooking
. It sounds like a step up from that. Then again, some people have zero interest in food.
