No no no - if you're coming from Brunswick and looking to go to Antietam Battlefield (in Sharpsburg, MD), you're going to have to ride about 12 miles north of Harpers Ferry on the canal towpath. When you get to the big Rumsey bridge (Route 34) over the towpath, there is a parking lot area with signage telling you to go to the right (it's uphill to the road). From there, you can ride on the road shoulder of Route 34 (Shepherdstown Pike) into Sharpsburg (about 3 miles into downtown). You'll take a left in downtown Sharpsburg onto Church street, and the Battlefield Visitor Center is another 3/4 mile up that road. It's all very well-signed, and should be extremely obvious when looking at a map.
