GORHAM â The state Bureau of Trails is using an excavator to fix drainage and washout issues on the Presidential Rail Trail, starting just west of Jimtown Road. This stretch of the 18-mile Presidential Rail Trail is also a segment of the Cross NH Adventure Trail (known as the xNHAT), an 83-mile bicycle route through 11 towns from the Maine border to the Vermont border, cobbled together three years ago by an energetic retiree, Marianne Borowski of Glen. Enthusiastic supporters of Granite State âcycletourismâ have donated money to pay for trail improvements, porta-potty rentals and publishing trail maps. The Bureau of Trails was authorized at a recent of governor and the Executive Council meeting to accept a $6,400 donation from the Cross NH Adventure Trail to rent an excavator to perform trail maintenance on the Presidential Rail Trail.
