Independent pet sitting is generally allowed for individuals who are at least 18 years old. This age requirement is in place to ensure that the pet sitter has the maturity and responsibility to properly care for the animals in their charge. Younger individuals may be able to pet sit under the supervision of a responsible adult or with the permission of the pet owner. **

GPS, or Global Positioning System, works by using a network of satellites orbiting the Earth to determine the exact location of a GPS receiver. The satellites continuously transmit signals that are picked up by the GPS receiver. By calculating the time it takes for the signals to reach the receiver from multiple satellites, the GPS receiver can triangulate its exact position on the Earth's surface. This information is then used to provide accurate location data, such as latitude and longitude, to the user. **

Yes, the location is GPS. GPS, or Global Positioning System, is a satellite-based navigation system that provides location and time information anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. This allows for accurate and precise location tracking and mapping. **

GPS can be very accurate, with modern GPS devices able to pinpoint locations within a few meters. However, the accuracy of GPS can be affected by factors such as signal interference, atmospheric conditions, and the quality of the GPS receiver. In urban areas with tall buildings or dense tree cover, GPS accuracy may be reduced. Overall, while GPS is generally very accurate, it is important to consider potential factors that may affect its precision in specific situations. **

I'm sorry, but as an AI text-based assistant, I do not have a physical GPS watch for children without a contract. However, there are several options available in the market such as the Verizon GizmoWatch or the TickTalk 4 GPS Smartwatch that do not require a contract.

Yes, GPS can be used on the iPad 3G without a SIM contract. The iPad 3G has a built-in GPS receiver that allows it to determine its location without needing a cellular connection. This means that you can still use GPS-based apps and services, such as maps and navigation, even without a SIM card or cellular data plan. However, keep in mind that without a data connection, the iPad won't be able to download map data or provide real-time updates, so it's best to download maps and data while connected to Wi-Fi before using GPS offline. **

Some people who find Halloween unnecessary are those who do not celebrate it for religious or cultural reasons. Others may feel that it promotes excessive consumerism or encourages children to engage in unhealthy behaviors like consuming too much candy. Additionally, some individuals may simply not enjoy the spooky or macabre themes associated with the holiday. **
