weed
Uh yeah, but ummmmm, no. Maybe if you're smuggling weed, but other than that, no.
Seems funny to see that Kingbear....
Back in the 60's I regularly spent the summers in Canada touring the eastern provinces from Ontario East....
But, each time I went, I towed the bonneville on a trailer and at the time, pot was at a premium up there and hard to get.
I did exactly the same thing although removing the entire foam pad and replacing it with about 3-4 lbs of premium bud, once across the border, a visit to the local bike shop and a new foam seat made it all work.
Fortunately at the time dogs were not an issue so it worked perfectly and provided me with income to finance the trip!
Aaahh, the good old days!!!
