I fly alone alot, just because it a 37 mile drive to the R/C club field, and a 1.5 mile drive to the local airport where I have permission to fly. It's a very small airport, that gets maybe two planes a week for traffic. I NEVER go out there without my cell phone, first aid kit, and my handheld aircraft radio. It is very relaxing to me to go out there in the evening after work, when the wind is calm, it's quiet, and I'm the only soul around. Flying alone can be just as safe as having someone with you, IF you make yourself follow all safety rules to the letter, and check and double check EVERYTHING!
