I have included the URL to a pretty neat site to predict Satellite availability in your area. It will tell you the best time of day and how many satellites will be available at given times. I used this yesterday and it was pretty accurate. Please know when you enter the site it will ask for your address or GPS coord. I put in my full address and then it gives me the satellite availability status for the current 24 hours. Just thought I would pass this along to others here and maybe someone would fine this useful.
