I finally took the plunge and have done some commuting. My PT summer job is 6 miles from home and has a bike trail all the way. I have ridden it and loved it but the job is at a golf course and it is too hard to tote golf clubs so I can head to the driving range after work 
I do ride my bike for errands, however, I have gone to the bank drive thru, the Post Office drive thru and I have a "Wicked Witch of the West" basket on the back that will hold a large size "green" grocery bag which I take into the store - anything that will fit in the bag I can take home.
A little funny aside - my DBF was on an out of town business trip, he walked to the bank and went to the drive thru - the teller refused to serve him because he wasn't in a car. He was told he had to go inside. Unfortunately the inside lobby was closed (as he already knew). After much fast talking on his part and deliberation on the tellers part she finally served him through the drive thru window. Without naming places it happened in an ocean front far Western warm state
It's about the journey and being in the moment, not about the destination
