Gaithersburg
Skip as a base unless you have a reason to be here (family, NIST, cheap hotel): 1 night, or use it as a car-based stop 25 min from Washington, DC.
Gaithersburg is a Montgomery County suburb of about 70,000 people, 25 minutes north of Washington, DC by car via I-270. It has a small historic Olde Towne, a rail station on the MARC Brunswick line, and the National Institute of Standards and Technology (NIST) headquarters. Most travellers pass through; those who stay come for cheaper hotels, family visits or the county fair.

Etiquette, safety and scams
Etiquette
- Greeting: Handshake and 'hi, how are you?' — reply 'good, thanks'; avoid: Treating the question as a real health enquiry
- Restaurants: Tip 18–22% and wait for the check; avoid: Leaving without tipping
- Personal space: Keep an arm's length in queues; avoid: Standing close to strangers
- Politics and religion: Listen more than you speak; avoid: Opening with hot-button topics
- Smoking: Smoke only in marked areas; avoid: Smoking near doors or in parks where banned
Scams and watch-outs
- MARC Brunswick line has no weekend service and few midday trains: check the timetable before relying on it.
- Many sights and restaurants sit in strip malls along Frederick Road and Shady Grove Road: plan by car, not on foot.
- Summer heat and humidity in Jul–Aug; afternoon thunderstorms are common.
- Prices are shown before sales tax; tipping 18–22% is expected at sit-down restaurants.
Standard US precautions: traffic on I-270 and Frederick Road, summer heat and thunderstorms, and unlit strip-mall car parks at night. Keep valuables out of sight in parked cars and use 911 for emergencies.
