I hope we do get a chance to swap some day.
The few times I've sent seeds across our common border, they always went through ... eventually. Sometimes fast and sometimes slowly.
I think I calculated once that we could have WALKED the seeds faster from Calgary to Seattle (or vice versa) than they went by mail including a long layover in Customs.
Well, maybe not - 1,000 km = 620 miles. 200 hours. 25 days at 8 hours per day at 3 MPH (ignoring mountains). Close, anyway! Only 8+ days if you could walk 24 hours per day.
