You will find it handy to keep an old blanket in your vehicle. You can use it in your trunk or cargo area when hauling dirty items. You can also use it to protect your roof’s finish if you are placing something on your roof rack. If you need to change a tire, you can lay it down to protect your clothing from mud or road grime.
If you’d like to increase your bike use, consider purchasing a bike trailer. While designed mainly to haul kids around with you, a bike trailer can also be used to bring home groceries, garden supplies, take-out food, small furniture, library books, or anything that can easily fit into the trailer compartment.
