To be honest I only take a plane in emergencies or if it is more than a days drive (8hrs). I live 2 hours from Philly and until it is more than an 8n hr. drive it is not worth flying anymore. When I add up the cost of driving both ways to Philly, cost of parking, The 2 hr. jerk around at the airport, the possibility of sitting on the tarmac for hours due to weather, the cost of tickets, the uncomfortable seats (I am 6'3" 300lbs.), lost luggage, extra charges for luggage, all the restrictions on what I can bring, rental car where I am going, and the fact it takes all day to get there. I can get there quicker driving for a lot less money and bring anything I need. Plus there is no hassle if plans change and I need to come back early or later.
Plus I love to see this county. I usually plan trips so I can see things I haven't seen yet along the way. I love stopping in cities getting out walking around, shopping, site seeing, and finding a nice place to eat. Plus I meet so many nice interesting people. It is nothing for me to spend several weeks driving some where.
