I am not sure how this is all viewed by whomever, but I am thinking about developing an insect spray.  Such annoying part of being outside at times.  Doubt but suppose I could try for a grant too.  I just think those ones at the store are too excessively poisonous and I want to make one that if by accident soak through skin, whatever, people would know what to do more often("Get a pillow") effects that are identifiable and safer.  I am real glad to meet many and well if you do have any info on buying different things, prices whatever...i use abine to block followers online if it helps and yes...I still use Linux too!  Work nice!
