If cost is an issue, you might want to consider a below ground pool with a liner rather than a gunite pool. Add a spa, decking, and high end equipment and you can easily be up in the $40,000 to $50,000 range, depending on size. Talk to a few pool owners and pool builders in your area for more detailed information.
One and a half hours is much too long to cook the chicken at 350 degrees F. The time your chicken will bake in the oven does depend on the internal temperature and the size of your chicken or chicken pieces. Generally I bake chicken at 350 degrees F. for 30 to 40 minutes.
The correct chicken cooking temperature is critical to destroying pathogens such as Salmonella, which is extremely heat-resistant and can cause severe illness. To safely destroy dangerous bacteria the internal temperature of cooked chicken should reach no less than 165 degrees Fahrenheit. This is the minimum temperature for safe cooking, however, for maximum safety a higher chicken cooking temperature may be preferable, particularly for breast meat and whole chickens. For whole chickens 180 degrees is a safe temperature, and 170 degrees Fahrenheit is safest for chicken breasts.
