Hit Four Birds Middle/Split Rock Loop yesterday. Did the 6 mile In and back version, first hike since last summer. Not a particularly inspiring hike, good views of lake disappear after the first half mile (might return past 3 mile point but wouldn't know), with 2-3 swampy/buggy areas passed through. Bugs were very bad yesterday, not sure if they're mayflies or what, but am covered in itchy bites today (and sore!). HOpe to be more active on site this summer
POST EDIT 5/1. The bites seem to be black fly bites, and my arms and legs (was wearing shorts) are covered in small itchy welts. So take precautions if you're considering this hike around now.
