Hi firearms fan...Nice going. Great to hear your helping out there. It definately needs more people doing this. The dump letter we obtained from Mission District was date specific, so it was only valid for 3rd March..The Sylvester road area actually falls under the Fraser Valley Regional District and they didn't respond to my request to help out with dump fees, even though they have a dump area close by...Thankfully Mission stepped up to the plate. I think they would want you to be part of a 'group' clean-up, but you can always call them and see how it goes....
I've pictures of our clean-up, but can't attach them to this thread..
