I have an Excel file with 500 parks that have free WiFi. The file contain hyperlinks to each park's website. All have websites. Either they advertise free WiFi or I received an email from them confirming that their WiFi was free to overnight guests. I had to restrict myself to parks with websites so I could get their address. Using their address I was able to obtain their latitude and longitude. If you import the file into MS Street & Trips, the balloon will show the hyperlink that you can click on and get that park's website. Please email me at firstname.lastname@example.org if you would like a copy. If you have downloaded my previous file, I suggest you replace it with this one.
