That looks like a nice variety, Alex -- sounds similar to "Australian Blue," which I grew last year and loved. I saw that a couple of the reviews on the Baker Creek site did say the plants were larger than they expected them to be... but, the good news is that after you get a few squash starting to grow on the vines, you can prune the ends off without hurting anything. You won't get as many squash as you would otherwise, but often the ones that form late, way out on the vines, don't have time to mature up here in the north anyway; and by pruning the vines the plant could put more energy into a few squash instead of all the vine and small immature squash. (and you don't really need to use rocks or anything, just move the vines around where you want them...)
Rick -- stop scaring the gardeners!
