See......where I really get my willies is taking - in your case - 26 x 10 (months) = 260 x $500 ($1000 is even more fun but EL dropped the price - a little) = $130k - actual investment of roughly $2600 (sure add in another $1k for gear) so make that $3600 but lets round up a bit just cuz to $5K and subtract $5k from $130k - - and grin and say "Oh Yeah Baby" - LOL
So the occasional GB going way south kinda is ok given the overall landscape and scope of this thing.
If I'm honest, I have developed an intense fetish for opening my freezer door in satisfaction. LOL
