You're exactly right...Mother Nature and the weather people have absolutely no respect for us climbers!!
One other comment since you're planning on camping at the Queen Mine on the way up to Boundary Peak...that will be a dry camp, so plan on hauling plenty of water with you in the car. If you hike up to the Kennedy Pass saddle to camp, you'll need to double up on your normal load of water so you have enough for the evening plus the whole climb and back down to your car. Not impossible by any means, especially since it's just a one-night stand but the last chance for water will be Benton or some other little town before you get to the Queen Canyon Road.
Speaking of no respect for climbers (or hikers!), it takes four 7.5-minute USGS quadrangles to cover the approach and summit of Boundary Peak. Why on earth do all these trails have to meander around the very corner of a map where you need not just one or two, but all four to figure out where you are??? Of course, you can do what I did and cut/paste the corners together from the .pdf maps you can download from the USGS store. I'll be happy to put that merged map fragment back on my web site and post the link if you'd like.
