Good Lord willing, I'll turn 60 next month.
I've had 2 major back surgeries over the past 25 years, L4 & L5 discs. That being said, back long ago I just grabbed up the bucket and loaded it up. Now that time has passed I've learned to categoriz buckets of WW's in 3 different catagories.
1. No problem, fairly light
2. Farily heavy, be Careful!
3. Oh hail naw! Don't even think about it. Use 2 buckets!
When I get them home, I back up to the garage door and get the 'Lil Red Wagon' up under the tailgate of the truck. A much easier way to transport them to and from wherever I need them after that.
