Brush pickup

[Chuck]

Hey all -

Another gardening-related question over here. I spent the last two weekends trimming bushes around my property that have not been maintained properly for years. As a result, I have 3 enormous piles of branches and clippings to get rid of. Does anyone know if this has to be tied up before putting on the curb, or can I just drag it out there and hopefully it will get picked up?

Thanks!

Chuck
