The best places are by CP Ham by Canal Park and going to the Allentown Hump off River Drive, Normally they don't bother you. Espically if you take your son or daughter with you
You can sit along the railing and they won't say anything at the Hump.... We already got chased out of CP Burn as a previous post said to stay off the N/S property and you are fine. The Hump crews are normally 3805, 3806, 3807 & 3808!! They talk on Ch.5 160.2450 ........ Good Luck
