I spend a lot of time in automotive assembly plants on concrete all day and I've been wearing Redwing 1242s and love them. Most of the guys I work with wear some type of Redwing boot.
1. I would echo the 180splitg3 with the thermacell. Seems to help out with bugs.
2. Dunhams usually has some decent deals on kids Camo if you don't care about it being top end stuff.
3. I hunted ladder stands as a kid in MI quite a bit. The two man stand work well for an adult and a kid.

An Alaska Guide Creations Denali should fit porros. Pretty big harness. They list the dimensions on their site so you can check if his binos will fit before you order!
