The low humidity makes colder temperatures somewhat more bearable in Colorado. I'm talking moderate cold, and not so much the dead of winter, when it gets really insanely frigid in the Rockies.

Also, consider Maryland's weird geography.

I've camped a fair bit with kayak on Chesapeake Bay and also bootlegging on Assateague Island. Very lovely and wonderful places. Saltgrass wilderness as far as the eye can see. Dophins, surf, wild ponys scrub pine and sika deer (size of great dane dogs). Truly ferocious and rather giant mosquitos and pesky sand fleas. Don't even THINK about the tarp shelter. Think bug netting and a floor.

Then there are the Appalachians in the western panhandle. Generally the same as Pennsylvania and Virginia. Mainly oak forests, with beech/maple at higher elevations. Little or no fir zone found in higher reaches of Smokies or New England. Hot sticky and fairly miserable weather for much of the summer. Hikes are best combined with swimming or frequent bathing in brooks. Insect life is bearable if you stay out of swamps and away from wet areas. You can use the tarp shelter with care in bug season. You may or may not regret.

Autumn-like weather can extend to Christmas or beyond, though a bit of snow might fall as early as November. On the highest hollows on the coldest winter nights, it will fall a tad below zero. Some winters will have no snow at all, and fairly mild temperatures.

Maryland is wetter than Colorado, but those summer afternoon showers in Rockies can be pretty persistent. Certainly thundershowers anywhere in Maryland can dump a rather large amount of rain in a short period. And you can get large coastal storms almost any time during the year, though in the summer and fall they're sometimes called hurricanes.
