I've done one large apartment complex. It was a complete pain in the ass dealing with the tenants. We had several run down our cones and through our drop zone. One got a cone stuck under their car and kept going. We even had caution tap up in one area and had a lady duck under it. I was in a tree cutting a limb loose and she walked right under me. Since that experience, I bid them high. Its worth a premium price to deal with the bs.
