Took a beekeeping course this weekend. Here's a pic of an awesome cart made by Paul Kelly (staff apiarist at U of G). Paul said he started with a hardware store double tire wheelbarrow and threw away the tub. You can tell something about Paul by the number of coats of varnish (looks better than my boat)
Paul says it's balanced so that with 4 full honey supers it's a one handed lift. I've added it to my todo list of 'someday' builds.
Here's a link to press on Paul (date unknown) that has an amusing story.http://www.uoguelph.ca/atguelph/01-09-19/people.html
