The next time you are in need of an overnight parking area try one of best kept secrets in Airstream Club International, Courtesy Parking. Currently approximately 500 fellow members offer free, overnight parking across the USA and lower Canada.
To use the benefit, all you need to do is contact the member in advance either by mail or phone and let them know your plans and wishes. In most cases, if they will be at home they will welcome you to stay over. Member contact information is included in the Membership Guide (for privacy reasons the contact information is not included in the map).
