It is still used. I forgot to write that in the preface and I did have trouble filming close to the river because I didn't realize it's hunting season and I did not bring any fluorescent vest so I took off about a quarter mile from the river on the road so I wouldn't have to walk through the woods and be at risk no but there is no flight restrictions over the river thereGreat shots of a great bridge. Did you have any issues launching near the St. Croix River?
Is this used much for rail traffic anymore?
