SMASH is my main launch site, I've scraped the waiver at 14,810 there (Simmed lower) and been over 10k 3 times, over 8k dozens of times. Biggest obstacle is the big icky, which is the main wastewater pond directly south of the launch site. Watch the winds, though in over a decade of launching there I only recall two or three launches with winds in that direction. The location 20 or so miles inland of lake michigan generally puts us under a jet stream most of the summer, most wind is from the west and south. Mostly farm fields. Bring a GPS locator though, there are a few tree lines that clock line of site from the launch site so don't plan on having eyes on landing.
