I live by there, and have to check my yard every time before I mow. I keep finding those small glass liquor bottles thrown in my yard as those people walk back towards 4th St. Ran over one once with mower and ended up with glass shards in my leg. I now have a collection of about 30 if SPPD needs proof.
Have also noticed lately those small plastic envelops (about 1" sq) in my yard with residual white powder.

Holy Mackerel, cbctsp -- that's horrendous! Take photos as you come across these bottles and small plastic envelopes! Do NOT pick them up bare-handed but wear gloves. This way you can turn them over to the police as evidence and they can be fingerprinted to id criminals making all of this noise, pollution [both in sound and trash], and harassment to neighbors and those who legitimately wish to enjoy the park as residents and families.

Such a sadness that you have to contend with this mode of crime in your abode across the street from what you'd perceived at purchase time to be a quiet, lovely park with the water just beyond it's boundaried edge. Praying that this situation is cleaned up soon!

Please contact the St. Petersburg Police Department when illegal activity is present. For an officer to cite the individuals for violations such as noise and trespassing it would have to be witnessed by them. You can reach SPPD by calling their non-emergency line at 727-893-7780, or call 911 for emergencies.
