My schedule is typically flexible, minus a meeting a need to be at by 9:00 AM on Wednesdays. My afternoon ride home may be from a different business address than the one in the morning because of my meeting schedule (e.g. Cameron Road area in AM and Lamar/45th in PM.
I am temporarily without a car and need an affordable way to get to and from work for a month. I work from home on Thursdays and would only need a ride M,T, W, F. Sometimes I add a work from home day so it may be less sometimes. Since I am without a car and cannot reciprocate driving, I am willing to pay more for gas to make up for that!! :) In addition, there may be days when I do not need a return trip if I catch a ride with a co-worker.
