Yep - I just couldn't find any eggs locally (mid-Atlantic US area), so I finally took a different tack, decided which week I would travel to look/buy, and then shopped to see where I could go to get a look at two or three candidates.
I was looking for a Trillium, really. I scheduled a look at an Eriba Puck along the route in Indiana (neat but a bit small for me and too much of a project), then continued on to Winnipeg where I was pretty sure I was going to buy a particular Trillium. I did have a Boler as a third option, and as it happened they had about five minutes in the early morning where I could stop by and take a look before they went to work.
So I zipped in there - it wasn't even completely light outside yet - and saw a little green-and-white Boler in their back driveway, behind a chain-link fence. It had that cute appeal of a dog at the pound looking out from the cage and saying "take me home" with its big brown eyes. I looked for five minutes, said I'd call them later, and then they rushed off to work and I went to look at the Trillium.
Well, the Trillium just wasn't the right one for me (not that there was anything horribly wrong with it, but it was at a premium price, so my expectations were higher), so I called the Boler folks back, wanting to take another look (and needing to get on the road back home). They couldn't make it back to meet me until that evening after work, which was going to put a big cramp in my schedule; but it also meant I had all day to look around for the adapter and relax.
I went back about 6:30 p.m. (yes, of course it was getting dark...), and looked at the Boler again. It was original, and nice and clean and dry. They'd owned it for 18 years! Sitting behind it, and looking mammoth, was a new Scamp 16 they'd recently picked up. After a bit of hemming and hawing about the paperwork (I hadn't realized that in Canada they don't have "titles," as we know them, but instead have "ownership" - long story but it all worked out in the end), I hitched up, got everything squared away the way I like it, and headed down the road with a "new," 35 year old trailer behind me.
I took it slowly, stopped a few times to check things over, and then only went to just a short way over the border back into Minnesota before stopping for the night. Next morning dawned sunny and W-I-N-D-Y--- and I was on my way! The trailer towed like a dream, and was amazingly "slippery" in the winds; no buffeting at all. I was pleasantly surprised.
Had a fine drive all the way home, even getting up to 65 mph without any issues after I settled in and got used to it. Not much traffic to speak of until I was in Pennsylvania and the mountains, by which time I was used to having the li'l guy back there.
I hope you have a great time picking up your K-line! Can't wait to see more of your unusual find.
