I spent the night at the Portal on July 1, and didn't think the skeeters were bad at all. Next day we hiked up to UBSL and still no real skeeter problems. I brought DEET, but the only time I put it on was during the descent from Russell the next day. Around dusk at Lone Pine creek the skeeters got a little annoying. But believe me, compared to past years the skeeters seems pretty light.
