Laurie Ladybug's Laundry Mystery Cache

Here's a middle school level math problem for fellow math lovers. There are two waypoints on the way to the final, all within 300 feet of each other in a quiet, scenic area.

One-third of Laurie Ladybug's family flew to the field with the purple poppies. Call that number P.
One-fifth of the family flew to the garden with the red roses. Call that number R.
Three times the difference between these two numbers flew to the wild wisteria. Call that number W.
And Laurie Ladybug went to the lake to do laundry.

If all of Laurie Ladybug's family flew home to help her with the laundry, they would meet here:

N 45 3A.BCD 122 5E.FGH where

A = (2xR) - W
B = W-P
C = W
D = P-R

E = R+W
F = R
G = P+1
H = P-1

Terrain rating is for the final. Terrain for waypoints 1 and 2 is one star/wheelchair accessible. The area can be busy during weekdays, but deserted on evenings and weekends. I recommend the latter.

If you see Laurie Ladybug, say "Hi" and maybe help with the folding.
