My friend Tom and I go to Ynyslas most Mondays.  We usually collect 2 bags, 2/3 full, as you know they get heavy and can tear. I figure we have missed out on about 8 Mondays this year, maybe 10. 

Tom is disabled, but loves to walk and carry, so he carries the bags, and I do the picking. 

We have our own little spot, and once that is done we move off to other parts of Ynyslas.
