This is going to be a real issue for me at some point, especially the ones I used in landscaping areas. Those may stay, minus some select ones.When we move it is gonna be a real job collecting them, probably need their own U haul truck.
Although, over the last decade or so I have started giving them away to people (a la Dan Hardy and his art) so I guess I've thinned it out a bit. I only regret a few, there have been a few that I said I would replace but haven't been able to. At least not affordably or easily.
