Saturn

Saturday I was going mountain biking and the Saturn was not wanting to pull out of the garage.... I was really upset because this was the probably one of the last times to get out and go for a ride.... anyhow when I tried to start it, it went completely dead.... no lights, no sounds... nothing ... it happened once again Saturday afternoon and now it is ok.... I checked the battery... it seems tight ..... I really don't like car problems... actually I really don't like any kind of problems... but car is at the top of my list right now!
