So you want to ride a bicycle as your main method of transportation in a non-bike-friendly American city, right?
I'd recommend setting up a living trust instead of a will. A will can be contested in probate court, but a living trust enjoys protections against that which wills do not. If you have dependents or even charitable organizations that you want to make sure get regular payouts from your estate long after your death, a living trust can often be the better option. An estate lawyer can give you more information than I can. I also recommend an insurance policy that will cover a closed-casket funeral in full.
