There are plenty of very nice public boat launches in MN but then again there are some rough ones to. To shallow, to deep, unprotected, boulders, busted up concrete and so on. Just curious to here or see photos of some of the gems you guys have had to launch at.
So far my vote goes for the Log House Landing (Copas) on the St croix just north of William O Brian. This one is a gem but I still like to launch there. Steep narrow road down to the landing turn around that has limited parking on both sides. Get on idiot not parking right and it can be very tight just getting in there. Get down to the turn around and once again gt some joker not parking right and you might not even be able to get turned around. Once turned around you get to back the trailer down the steeper yet gravel upper part of the gravel ramp. This runs parallel to the river. At the bottom of this its just a quick jack knife of the trailer and you are in the water. The good part about this landing is it drops off into deeper water. 4wd is a must for getting the boat back out and up the ramp.
You can zoom in on this little landing from this link. Ill try to get some better photos of it next time Im over.
