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.
--You also must arrive at least two hours prior to flight time, since you will be required to sign various forms and get a gate pass to get you through security. --In some cases the airline might not be able to have you go through to the gate, so be prepared to have an airline representative get them onboard.
