Sorry to hear this Jake, it has been going on for too many years and there really is no solution to it. Chilliwack has so many what some call homeless. Saying that I doubt it was one of them to get to where you were would take a vehicle to access it. Although there is camp everywhere in the Chilliwack River Valley.
I just park in heavy foot traffic areas or subdivisions and do a bit more walking. I have even thought of buying a bike and travel that way but that could see the bike stolen as they did to the Leaf Mobile when I was at church no less.
Since then I have an immobilizer in the truck and of course as everyone knows there is so much junk in the cab and back they would think I am homeless too and
am one of them with nothing worth stealing.

All we can do is watch out for each other as much as possible.
Once again don't give up the hobby you enjoy so much.
I was out for 30 minutes this AM at Gwyn's run but nothing heard of three taken elsewhere, water lovely.
I think I will try Aarons hotspot this afternoon but most likely too low but rain is on the way, maybe should try for cutt's.
