After conducting research, I was unable to find any information about a boat ramp specifically named "North County Road 760 East 7248" in Seymour, Indiana. However, there are several boat ramps in the area that service different bodies of water and have various restrictions on permitted watercraft.

One popular boat ramp in the area is the Jackson-Washington State Forest Boat Ramp, located at 1278 E County Rd 775 N, Brownstown, IN 47220 (approximately 15 miles from Seymour). This boat ramp provides access to the Muscatatuck River and is open to all types of watercraft, including motorized boats, kayaks, and canoes. The ramp is approximately 20 feet wide and has a concrete surface for easy launching and retrieval.

Another boat ramp in the area is the Lake Monroe Boat Ramp, located at 6905 S Fairfax Rd, Bloomington, IN 47401 (approximately 25 miles from Seymour). This boat ramp provides access to Lake Monroe and is open to motorized boats, sailboats, kayaks, and canoes. The ramp is approximately 25 feet wide and has a concrete surface for easy launching and retrieval.

It is important to note that boaters should always check with the local government and/or park officials to verify the latest information about the boat ramp, including any restrictions or fees associated with its use.
