Very sorry to hear that,
I too had a break in - the same spot about 3 years ago and lost alot of stuff (they tried to steal the car too). I was left out of pocket and with a higher insurance premium as a result.
It is a VERY POPULAR spot for thieves - i know of many of my freinds who have had stuff stolen from that place. Don't just lock it away, take it with you.
I will certainly scout the area as I visit every week or so.
Regards and Hugs
