At just over 2,500 feet, it's the highest point on the TMT. In spring, look for red currant blooming here. From Tom's Crossing, the West Tiger #2 Trail heads steeply uphill providing another way to reach that summit. Continue down the TMT on many switchbacks and, in about 0.3 mile, note the junction with the K3 Trail.
I rarely show up more than 1.5 ahead of time. Another idea: technically, the ticket counters usually open 24 hrs before your flight, and sometimes this is the only way to easily get special seats like exit rows.
Luckily, today there are a variety of ways to minimize the time you need to arrive at the airport in advance to make your scheduled departure. Arriving two hours before a flight isn't always necessary (provided you don't require extra time or aren't a part of a group). There are some excellent strategies you can implement to skim that two hour-protocol down to one.
