Here is a interesting idea that I ran across, it has some good as well as some bad attributes. The price he wants for this thing is very high but the idea is sound. Wouldn't be hard to make but I have read about a lot of parks prohibit these on the trail but studies say that it does not harm the trails. There is a law that prohibits mechanical devices used in park areas including dear carts, dollies, etc. Any thoughts? Do a Google for DIXON ROLLER PACK reviews.
