Most summer tourists to the spectacular National Park are back home at jobs or schoolbooks. With the crisp autumn weather, seniors can enjoy a leisurely, less-crowded visit. There are soaring cliffs, magnificent waterfalls, deep valleys, endless meadows, giant sequoias, wildlife and never-ending scenery. For schedules, fees and other info, go to www.nps.gov

Q: It’s very generous and cost a lot of money, but the trip scares us. We’ve always been small-town folk and need some advice. What do you recommend? LRK, Canadensis PA

A: NYC can be both enjoyable and scary. Keep checking websites about the current city scene, both positive and negative. Of course, the best warning for seniors is always to stay in well-lighted areas at night, including Broadway, Times Square and theater district. Also keep wallets in buttoned down or zipped front pockets, and purses strapped and held securely under an arm.

OK to point your camera and smartphone to record NYC adventures, but be aware especially at Times Square where costumed characters and musicians hang out. If you pose with any, they’ll expect $5 or more. Legally, you don’t have to pay, but they’re there to make quick bucks and will plead if you walk away. Don’t buy overpriced CDs, DVDs or other street peddler products. They may be blank, defective or contain bad copies. Whatever your concerns, relax and enjoy the fascinating city!

All senior flyers have experienced it. The disruptive guy in the next seat had too many Martinis in the airport bar. These days, the rowdy behavior is also happening when a large noisy group is on the same flight. It often occurs after holiday parties, family reunions, business conferences and college sports events.

If you’re traveling with a celebrating group, be sure all participants are aware of the cost of unruly and desructive behavior on flights. Not only could it result in big fines, you may also get kicked off the aircraft and headed for the hoosegow. www.theguardian.com/travel/2018/sep/19/partygoers-on-flights-warned-excessive-drinking-will-lead-to-hefty-fines

With thousands of homeless wandering downtown, street dangers in the City By The Bay is now at a constant high level. The recent crime happened when reporters set cellphones, purses and other items in a parked car that were shown on video as they were stolen. The fast-working, window-smashing thieves were not caught.

When travels take you to San Francisco and any other large world city, always obey personal safety rules. Keep your parked car locked, preferably in a commercial garage. Carry wallets in buttoned or zipped pockets. Keep strapped handbags secured under elbows. Always be alert, and at night, walk only with at least one companion on well-lighted busy streets.
